2-year-old baby milestones: Development, growth, speech, language, and more

As your baby turns two, you might marvel at how quickly time flies. In a few words, the days of baby cooing and taking first steps are now over.


Now, you’re witnessing the emergence of a little person with their own personality, preferences, and quirks.

At this age, your child is hitting developmental milestones across various domains – physical, cognitive, social, and emotional. Understanding these important milestones can help you support your child’s growth and address any concerns that may arise.

Your 2-year-old's developmental milestones


As your child grows, they will reach many developmental milestones that highlight their average growth in various areas.

Let’s explore what common milestones children can expect in terms of physical development, movement, coordination, language, and communication over the next year.

Physical development

As a 2-year-old, your child is a whirlwind of activity, constantly on the move. This is a crucial time for physical development as their motor skills become more refined and coordinated. You might notice that your toddler is more stable on their feet, capable of navigating various surfaces and even attempting to jump.

Here’s what you can typically expect in terms of physical skills milestones.

  • Walking and running: Your child is likely walking confidently, and running might become a favourite pastime.
  • Climbing: Expect your little one to start climbing onto furniture or playground equipment, showcasing their increasing strength and coordination.
  • Fine motor skills: Activities like stacking blocks, turning book pages, and scribbling with crayons are becoming more controlled and purposeful.

Supporting your child’s physical development can be as simple as providing safe spaces for them to explore, and encouraging play.

Movement and coordination

Your 2-year-old is likely developing a sense of independence through their growing physical abilities.

Their movement and coordination skills are rapidly advancing, allowing them to explore the world at their own pace in new and exciting ways. Here are some key milestones to look out for.

  • Running and jumping: By now, your child may be able to run with improved balance and coordination. They might also start experimenting with jumping, though it may take some time to get both feet off the ground simultaneously.
  • Kicking and throwing: Simple games like kicking a ball or tossing it back and forth can become enjoyable. These actions help improve their hand-eye coordination and gross motor skills.
  • Climbing: Climbing up and down stairs with assistance or even on playground equipment is typical at this age. This can help strengthen their muscles and improve their coordination.
  • Dancing and imitative movements: Your toddler might enjoy dancing to music or mimicking your actions, which is a fun way to practice balance and coordination.

Language and communication

As a 2-year-old, your child’s language development, and communication skills are blossoming. This period is marked by a significant leap when your child develops speech and use of language, making interactions more dynamic and engaging.

Here are the key aspects of their language and speech development.

Vocabulary and sentence structure

  • Vocabulary explosion: Around this age, children typically experience a rapid expansion in their vocabulary. They may learn new words daily, often surprising you with how much they know.
  • Simple sentences: Your child may start to string words together to form simple sentences, usually two to three words long.
  • Naming and describing: Expect your child to start naming familiar objects, people, and animals. They might also begin describing things, such as saying “Big truck” or “Red ball.” Try to play children’s music to help them develop their word understanding.

Understanding and responding

  • Following instructions: Your toddler will improve at following simple instructions, such as “Please pick up your toy” or “Let’s put on your shoes.”
  • Answering questions: They may begin to answer simple questions about their experiences and preferences, like “What do you want for a snack?” or “Where is your teddy?”
  • Expressing needs and wants: Communication becomes more purposeful as they learn to express their needs and desires more clearly, reducing frustration for both you and your child.

Social and emotional development

As your child reaches two years old, their social and emotional world expands, as do new and exciting abilities.

This age group of children are starting to understand their feelings and the feelings of others – learning how to interact with the people around them. Here’s what you and your child can expect in terms of social and emotional milestones:

  • Parallel play: This age group often engage in something called parallel play acts, where they play alongside other children older, younger or their own age, without directly interacting. This is a normal stage of their social development and helps them become comfortable around peers.
  • Sharing and turn-taking: While sharing might still be a challenge, you may notice your child beginning to understand the concept of taking turns. This can be encouraged through simple child play, games, pretend play and activities.
  • Showing affection: Your child may start to show affection towards family members and close friends, offering hugs, kisses, or cuddles. They are also likely to express preferences for certain people and might show anxiety around strangers.
  • Self-assertion: At this age group, most toddlers will often begin to assert their independence with a newfound determination. For instance, your child might insist on doing things themselves, from choosing food or his or her own clothes, even if they aren’t quite capable yet.
  • Recognising emotions: Your child is starting to recognise and label basic emotions, such as happiness, sadness, anger, and fear. They might also repeat words like, “I’m happy” or “I’m mad,” and will begin to understand these feelings in other children and adults. They could also express these during pretend play.
  • Temper tantrums: Temper tantrums can become more frequent as they navigate their emotions and test boundaries. This is a normal part of development as they learn to manage frustration and disappointment.

2-year-old's health and safety


As a 2-year-old, your toddler becomes more active and curious, and their health and safety remain paramount. Here are some key aspects to focus on:

  • Regular check-ups: Keep up with scheduled visits to your GP or child health nurse to monitor your child’s growth and development. These check-ups are essential for tracking milestones and catching any potential health issues early.
  • Vaccinations: At two years old, it’s important to ensure your child is up to date with their immunisations.
  • Healthy diet: A balanced diet is crucial for your toddler’s growth and development. Offer a variety of foods, including fruits, vegetables, grains, and proteins. Limit sugary snacks and drinks to promote good eating habits and help with disease control.
  • Oral health: Start teaching good oral hygiene habits by brushing your child’s teeth twice a day with a small, soft-bristled toothbrush and a pea-sized amount of fluoride toothpaste. Regular dental check-ups are also important to ensure healthy teeth and gums.
  • Childproofing: Ensure your home is safe by childproofing cabinets, securing heavy furniture, and covering electrical outlets. Keep small objects, sharp items, and hazardous substances out of reach.
  • Supervision: Always supervise your child, especially around water, whether it’s the bathtub, a pool, or any other body of water. Drowning can happen quickly and silently.
  • Car safety: Use a properly installed car seat appropriate for your child’s age, weight, and height. Always ensure your child is securely buckled up during car rides.
  • Playground safety: Check that playground equipment is safe and suitable for your child’s age and abilities. Stay close by to supervise as they play.


2-year-old's sleep


Adequate sleep is crucial for your 2-year-old and their growth, development, and overall well-being. At this stage, establishing a consistent sleep routine and addressing common sleep challenges can help ensure your child gets the rest they need.

Here’s what you need to know about your two-year-old’s sleep patterns and how to support healthy sleep habits.

How much sleep does a 2-year-old need?

A typical 2-year-old needs about 11 to 14 hours of sleep daily. This usually includes one nap during the day and a longer stretch of sleep at night.

  • Nighttime sleep: Most two-year-olds sleep about 10 to 12 hours at night.
  • Daytime nap: A nap lasting about 1 to 2 hours during the day is common for toddlers at this age.

Establishing a sleep routine

Creating a consistent bedtime routine can significantly improve your child’s sleep quality and help them settle down more easily at night. Here are some tips for establishing a bedtime routine.

  • Set a regular bedtime: Aim to put your child to bed at the same time each night to help regulate their internal clock.
  • Create a calming pre-sleep routine: A warm bath, reading a book, or singing a lullaby can signal to your child that it’s time to wind down.
  • Keep the environment sleep-friendly: Ensure the bedroom is dark, quiet, and cool. A comfortable sleep environment can make it easier for your child to fall asleep and stay asleep.
  • Managing sleep transitions

As your child grows, their sleep patterns and needs may change. Managing these transitions smoothly can help maintain healthy sleep habits:

  • Transitioning from two naps to one: Around the age of two, many children move from two naps a day to one longer one (maybe an afternoon nap). This transition can take a few weeks. Gradually shifting the afternoon nap time and bedtime can help ease this change.
  • Adjusting bedtime: If your child consistently wakes up too early or has trouble falling asleep at night, try adjusting their bedtime slightly earlier or later.

Dealing with sleep regressions

Sleep regressions are temporary disruptions in a child’s sleep pattern during various developmental stages. At two years old, a sleep regression might be linked to milestones like learning new skills or experiencing increased separation anxiety.

  • Stick to the routine: Maintaining a consistent sleep routine can provide comfort and predictability for your child during a regression.
  • Offer reassurance: If your child is experiencing separation anxiety, providing extra comfort and reassurance can help them feel more secure.
  • Be patient: Sleep regressions are typically temporary. With time and consistency, your child’s sleep patterns should return to normal.

2-year-old milk considerations


As your child grows, their nutritional needs evolve. For your 2-year-old, milk continues to be an important part of their diet, providing essential nutrients like calcium and vitamin D.

  • Transition to cow’s milk: If your child hasn’t already transitioned from formula or breast milk to cow’s milk, now is the time. Full-fat cow’s milk is recommended until age two, after which you can switch to reduced-fat varieties if your child is growing well.
  • Daily intake: Aim for about 350-500 ml of milk daily. This helps ensure they get enough calcium without filling up too much, leaving room for a balanced diet of solid foods.
  • Other sources of calcium: In addition to milk, incorporate other calcium-rich foods like cheese, yoghurt, and green leafy vegetables to meet their nutritional needs.

How can I help increase my 2-year-old's learning and emotional security?


Supporting your toddler’s learning and emotional security at this age is crucial for their development. Here are a few quick tips.

  • Engage in play: Play is a powerful learning tool. Interactive games, puzzles, and imaginative play help develop cognitive skills and creativity. Play enables toddlers to explore and express their emotions and practice managing them.
  • Read together: Reading books enhances language skills and strengthens your bond. Choose stories that are engaging and age-appropriate.
  • Provide consistent routines: Stability and predictability in daily routines give your child a sense of security and help manage expectations. Regular routines help toddlers feel safe and in control, which is key for healthy social-emotional development.
  • Offer emotional support: Be responsive to your child’s needs and emotions. Validate their feelings and provide comfort to build trust and emotional resilience. Setting and enforcing age-appropriate rules consistently can also help them feel secure and understand boundaries.
