My child is 18 months. They understand 90% of commands and respond well. When asked a question they understand enough to say yes or no. They are also very good at communicating what they want by pointing and explaining through gestures.
The issue is their vocabulary is quite limited. Their name, mummy, daddy, hi, bye, thank you, yes, no, one, two, three, cuddly toy name, baby, oh no, boo, cheers & banana.
I honestly do not know how to increase their vocabulary. My mother has suggested that next time they point to something to pretend not to understand and tell them "you need to tell me what you want".
Can anyone help or have any suggestions?
