whether your child can do the following:
say more than 6 distinct words naming objects clearly enough to be understood by a stranger;
point to body parts in response to verbal instruction (ie. where's your nose?);
use a spoon competently to feed themselves;
spontaneously make animal noises in response to a picture in a book (eg. miaow at pic. of cat).
I only ask as dd2's development is a bit delayed, and I can't remember whether 18month olds can usually do these things.
Thanks!
