Your toddler has grown into a child ready to learn in preschool! It is exciting to see how much they learn each day. Each child will meet milestones in their own time. If you have any concerns about their development, talk with your pediatrician.

Development at age 3

Physical 

  • Jumping, running, and climbing playgrounds are becoming their favorite activities.  
  • Your child’s fine motor skills have come a long way, and they can probably string beads and build blocks.  
  • Encourage them to color pictures or cut paper with safe scissors to further develop the tripod grasp.  
  • Potty training can be tough. Give yourself and your child some grace. There may be some trial and error before you find the method that works best.  

Language  

  • They have a vocabulary of around 200 words and love to communicate with you through telling stories and asking questions.  
  • Strangers should be able to understand most of what your child tells them.  
  • Telling you what opposites they see, like small or big, is a great way for them to communicate with you. 

Cognitive  

  • Figuring out how to make toys work, do small puzzles, and build structures is a great learning experience for them. 
  • Your child will avoid touching hot objects, like the stove, when warned.  
  • They’re learning colors, the alphabet, and basic numbers. 

Emotional and social 

  • At this age, kids move from playing next to each other to playing with each other. They may even have a few favorite friends.  
  • Sharing is hard for kids and may cause a few tantrums while they’re still learning better ways to express their emotions.  
  • They’re ready to further develop cognitive and social skills by going to preschool. 

Development at age 4

Physical 

  • Your child is learning new skills, such as skipping, somersaults, catching, and throwing. This is a great time to play outdoors together. 
  • They should be able to get dressed by themselves.  
  • Drawing with a pencil between their thumb and forefinger is a fun activity. Your child may try drawing people and telling you stories about their pictures. 

Language 

  • Your child can speak in sentences and use five or six words in each sentence. 
  • They can say their first and last names. 
  • You may hear them singing favorite songs — join in or record a fun video! 

Cognitive 

  • When reading together, your child will be able to predict what will happen next.  
  • They’re learning to count and recognize numbers and letters. You can have them practice writing their numbers and letters in pudding or shaving cream! 
  • They’re also learning to follow three-part directions. 

Emotional and social  

  • There still may be some meltdowns, but your child is learning to manage those big emotions with your guidance.  
  • They’re showing empathy and want to comfort others who are hurt or sad.  
  • They will enjoy pretending to be someone different, like a teacher or superhero, or playing dress up. 
  • Kids love to help adults. Show them how they can help around the house!
