These developmental milestones show some of the skills that mark the progress of young children as they learn to communicate. If your child is not meeting one or more of these milestones, please contact your local Preschool Speech and Language Program. To see these milestones in another language, please visit the Ministry of Children, Community and Social Services website here.

Quick Tips

Here are some tips on how you can help your child develop speech and language skills. Try some of these suggestions to help your baby/toddler interact or help your child use words to solve problems, make choices, describe objects and events and share ideas.

Babies like it when you:
  • Get down to their level so they can see your face. This tells them that you’re interested in what they’re doing and saying. It makes it easier to interact with you.
  • Repeat the sounds they make. Babies enjoy making noises, and like it when you imitate them over and over.
  • Sing and laugh, especially when you are feeding, bathing, and changing them. Remember to talk to your baby throughout the day about things you do and see – “Mommy’s putting on her coat”, That’s a big truck”
  • Tell them the names of the objects they are looking at and playing with. Babies are interested in exploring and learning about new things, and like to hear what things are called.
Toddlers like it when you:
  • Let them touch and hold books while you point to and name the pictures.
  • Use real words instead of baby talk – “give me” instead of ta ta or “bottle” instead of baba.
  • Take the time to listen to them – they want you to hear all of their new sounds, words and ideas.
  • Give them simple directions to follow – “Go find your red boots”.
  • Use lots of different words when you talk to them – opposite words like up/down, in/out; action words like “running”, “splashing”, and descriptive words like “happy”, “big”, “little”, “clean”, “dirty”.
  • Encourage them to play with other children – at the library, play groups, park.
Three-year-olds like it when you:
  • Give them different materials to encourage drawing and scribbling, including chalk, pencils, crayons, markers, finger paints.
  • Use descriptive words such as colours and opposites (hot/cold, big/little, fast/slow) as well as action words (flying, splashing, running) when you are talking with them
  • Give them extra time to share their ideas.
  • Give them choices – about what foods to eat, toys to play with, clothes to wear.
  • Model correct sounds and grammar for them – child says “he wunned” and you say “yes, he ran”.
  • Read books that are predictable and repetitive – pause to give the child a chance to fill in the words and phrases.
  • Play and pretend with them! They may like acting out scenes from their favourite videos, pretending to eat in a restaurant or to be a teacher or firefighter.
Four-year-olds like it when you:
  • Give them lots of opportunities to play with other children – at the library, the park, the Early Years Centre. Sometimes they like having just one or two friends over to your home to play.
  • Point out words in books and run your finger under words while you read to them.
  • Talk about the order of events – describe what happens first, next and last – “first we wash our hands, then we have a snack and last we put our dishes in the sink”.
  • Encourage them to tell their own stories – by asking them to tell you about their day, to describe a movie they watched, to tell you about their favourite book. Read books with rhyming words – “mouse/house”, and point out sounds at the start of words – “Mommy starts with the ‘mmm’ sound – that’s the letter M”.
Five-year-olds like it when you:
  • Use new and more complex words – “before/after”, “rough/ smooth”, “easy/difficult”, “between/beside”, “same/different”.
  • Talk about numbers and the quantity of objects – “a lot/a little”, “more/less”, “one/many”.
  • Ask them to predict what will happen next – “What do you think will happen when Sam opens his birthday present?”, and explain the reasons behind choices – “Why do we need to wear our coats today?”
  • Take turns telling each other stories using the pictures in books – children like to hear you talk and then want a turn to create their own version of the story.
  • Let them help plan events. Talk about what you need to do before a birthday party, or how to get ready to go to the zoo. Ask your child “why” and “how” questions as you talk.
  • Ask them to help. Your child will enjoy helping you bake cookies, set the table, sort laundry, etc. Give them instructions and see if they can tell you the steps.
