4 years 5 months old

At this age, your child will be pretty active, and loves playing outside!

Physical Development

Your 4 years 5 months old child is pretty active at this age. You might even have a hard time keeping up, since he love to run, jump, climb, and do all sorts of physical activities. It might be tiring for you as a parent, but this is a good thing since it means that your child is growing up healthy and strong. Here are some of the other skills in your 4 years 5 months old child that you might encounter:

  • Can do a somersault
  • Is able to hold a pen and grasp small objects
  • Is able to kick a ball
  • Can throw and catch balls
  • Can hop around
  • Is able to stack 10 or more blocks

Parents should always remember that playing is an important part of their child’s development. So it’s a good idea to encourage your little one to play with other kids, or explore safe play areas such as playgrounds etc. These activities would help develop his physical ability, and can also keep your little one fit and strong.


  • Be sure to make going outside to play a daily activity, to help boost your child’s physical development.
  • Buy puzzles, building blocks, and other creative toys to train his manual dexterity, as well as his lateral thinking.
  • You can also teach your child to swim, as it’s a great activity that helps keep your child fit and strong. Just be sure to keep your child supervised at all times, and be sure that there’s a lifeguard whenever you and your child go swimming.

When to Talk to Your Doctor:

Parent’s shouldn’t immediately worry if they notice anything different about their child. The best thing to do would be to visit a doctor to get a proper consultation. Additionally, these are some signs to look out for:

  • If your child can’t stack 10 or more blocks.
  • If he has trouble hopping, or balancing on one foot.
  • If he has trouble holding small objects, such as a pencil, or crayons.

Your child’s brain starts to absorb a lot of information at this age, and he’s constantly learning new things.

Cognitive Development

Kids this age ask a lot of questions and while this might frazzle you at some point, know that this is how they learn and absorb new knowledge. In fact, asking questions is a sign of a child who will always love learning, so go ahead and help your child find the answers… until the next question!

Your child can also follow more complex commands at this age, which is indicative of his rapidly developing cognitive skills. 

Here are some cognitive milestones to expect in your 4 years 5 months old child:

  • You can easily have a conversation with your child.
  • Your little one can already do some simple chores, such as picking up his toys, or keeping his room clean
  • At this age, children find it easier to pay attention, so this is a good time to teach your child new things
  • He already has a basic grasp of time, and can recall past events easily


  • Constantly talk to your little one. This can help build his vocabulary, and since he can pay more attention, he will easily remember the things you teach him, building memory skills.
  • This is also a good time to start teaching your child a second language, if you wish. Children’s brains can adapt easily, so he can easily learn a new language while he’s young.
  • Nurture your child’s love for reading, as this is crucial for strong literacy skills. 
  • Instead of regular toys, invest in STEAM (Science, Technology, Engineering, Arts, Maths) toys, as these encourage cognitive development in your child through play. 

When to Talk to Your Doctor:

  • If you sense that your child’s attention span is still limited
  • He still can’t pronounce simple words
  • If he has a hard time following simple instructions, or if he doesn’t listen when you tell him to do something

Your child can easily socialize with other kids his age, and won’t have trouble making new friends.

Social and Emotional Development

In terms of social and emotional development, your 4 years 5 months old child is starting to have more empathy. This means that he can understand how other people feel, and can understand how his actions can impact other people. This also means that your child can socialise better with other kids, and it’s easier for him to make friends.

If previously, your little one had a hard time sharing his toys, then you’ll find that at this age, it’s much easier for him to do. He’s also much more in control of his emotions, and has fewer tantrums in general.

Here are some developments in this sphere to look out for in your child:

  • He has no problems doing things on his own, and is more independent
  • It’s much easier for you to manage his behavior, since he can understand rules and guidelines that you set
  • He constantly looks for other kids to play with, and has little trouble making new friends
  • He has fewer tantrums, and will rarely shout or scream
  • Your child can also speak more clearly, and can handle himself when talking to other people


  • Try setting up playdates with other kids, so that your child can interact with other kids around his age
  • Implement some basic house rules, such as cleaning up after playing, or taking a bath before going to bed
  • Encourage independence by letting your child do simple tasks such as dressing himself, or eating by himself without your help
  • It’s a good idea to focus on teaching him social skills such as sharing, empathy, respect for others, and listening 

When to Talk to Your Doctor:

If your child shows any of the following signs, then it’s a good idea to discuss it with a doctor to find out what might be the cause of the problem.

  • Has a hard time getting along with other kids, or starts picking fights with them
  • Prefers to play alone, and gets frustrated or annoyed when other kids try to play with him
  • Has extreme separation anxiety when left alone, such as in a daycare, or in a playschool
  • If he doesn’t like talking or engaging with other people, even you, and prefers to be alone by himself
  • Still throws intense tantrums

At this age, children find it easier to learn and understand new words.

Speech and Language Development

At this age, your child’s ability to learn new words goes into overdrive! This means that he will be constantly asking questions, talking, and trying to learn as much as he possibly can. It’s not uncommon to see your child pointing at different signs, and asking what those signs say. 

Your child will also sometimes point at objects, and ask you what they are called, so be ready with some satisfying answers. All this chatter is indicative of rapid speech and language development. 

Here are some other milestones that you can expect:

  • His vocabulary will expand at this age, and he will try to use the new words he learns as much as possible
  • He has no trouble speaking in complete sentences, and he can easily have conversations with people
  • He can also answer questions when asked
  • Your child can easily remember new words that you teach him


  • Focus on expanding your child’s vocabulary, as well as practicing having conversations with him
  • Flashcards are a good way to teach new words and concepts to your child. Make sure that the flashcards are colorful and visible, and that the text can easily be read
  • Don’t worry if your child has some trouble using new words in sentences, be sure to teach them how to use those words properly so that he can remember the meaning
  • When you read with him, point at the word you’re saying, so that your child learns to associate how the word sounds, with how it’s written. 

When to Talk to Your Doctor:

  • If your child is unable to say his name
  • If he has trouble remembering any new words that you teach
  • He still has trouble speaking in complete sentences
  • If he has trouble talking, or has a hard time understanding what you’re trying to say 

In case your child shows any of these warning signs, don’t be afraid to consult your doctor about it. They would be able to provide the best advice and approach to help address your concerns regarding your child’s speech and language development.

Along with exercise, having a proper diet can help boost your little one’s development.

Health and Nutrition

At 4 years 5 months old, your child will be about 101cm tall, and weighs about 15kg. However, do not be worried if your child is a bit smaller, since both height and weight can also depend on genetics. The thing to remember is to provide your child with the right amount of food and nutrients in order to help boost his development.

Taking naps in the afternoon, and having at least 9 hours of sleep every night is also important. This helps your child’s body and brain grow. 

Here’s a handy chart showing some of the important nutrients your child needs:

Nutrient Amount Needed Daily What To Feed Them
Protein 20.1g (the size of your child’s palm) About 3 one-inch cubes of lean meat, such as pork, chicken, or fish per meal
Fat 25g (around 1 tablespoon) 1/2 cup of avocado as a snack
Fibre 25g (around 1 tablespoon) 1 cup of cooked pearled barley per meal
Calcium 600mg (2 cups) Around 2 tbsp. of cheddar cheese per meal

  • Polio (IPV) (4th dose)
  • Measles, mumps, and rubella (MMR) (2nd dose)
