At a glance

  • Three-word sentences carry detail the shorter ones could not.
  • Counting gets applied to actual objects, not only recited.
  • Both feet leave the ground together in a genuine jump.
  • Colours get named, with one favourite used most often and most wrongly.
  • Questions and statements start sounding different from each other.

The third year opens with more words in a row. Two-word requests stretch to three, and the extra word usually carries the detail that was missing before, so wanting milk becomes wanting more milk now.

Counting attaches itself to objects for the first time, colour names settle onto colours, and both feet finally leave the floor together. Your child sounds and moves noticeably older than a few months ago.

What is new this month

A third word changes what a sentence can do. Two words can name and request, while three can specify who, how many, or which one. The grammar stays loose and small words get dropped, which is expected while vocabulary is growing faster than the rules for arranging it.

Counting objects is a real advance on reciting numbers. It means touching or pointing at one thing per number word and stopping when the objects run out, and understanding that the last number stands for the whole set is a separate idea that takes longer to arrive. Things that stay still, such as stairs or grapes, are far easier to count than things that move.

Jumping and colour naming have little in common except that both suddenly work. A jump needs enough leg strength to lift the whole body and enough balance to land it, and once it arrives it gets done constantly and everywhere. Colour names attach unevenly, often with one word covering everything before the others separate out.

Week by week, in the app

Our paediatric specialist wrote one thing to notice and one thing to try for every week of the first three years. Here is what this month covers. The app works out which week your child is in from their birth date and brings each one to you on the day.
