When did your toddler begin to recognise between mummy daddy nanny etc . DS is 21 months and is behind with his speech yet to say a proper word did say something that sounded like dad a few months back but nothing at all since ! When we say for example where’s daddy he doesn’t know I find this a bit concerning because both my girls know this from around 12-15 months ? And one of them was also behind with speech and went to a SLT. He babbles an awful lot and has good eye contact and very good understanding will follow simple instructions . Just wondering when your child was able to point to mummy daddy etc when asked. I’ve been told that boys are slower with their speech multiple times even before DS was born!
