Here is the link to the YouTube video where Nicola Lathey from The Owl Centre talks about what children at the age of 12 to 18 months are up to.
She covers understanding, expressive language, social skills and gives some tips on how to help their speech, language and communication.
This is the age when parents may start to notice differences between one child’s development and another.
Here is the handout on development at 12 to 18 months that you can download here.
