My ds4 is 3 in August, he doesn't speak v much. He can say all the family names (not perfectly), juice, please thank you, sorry, yes, no wee wee poo. And count to 10. He will not say a whole sentence tho. I have taken him to a doc who tells me that because when ds was 4 months he nearly died from pneumonia that his chest and throat are slightly behind in development. His right lung was full of puss from infection and his left was only 24 hours from collapse, he had a feeding tube and oxygen for 7 days. Though all of this he is still a strong and big (he is the size of my ds2 who is 6).
People I know from the school will talk to him and then say to me why isn't he talking yet blah blah. I don't wanna tell them his life story it has fuck all to do with them.
He starts pre school in sept, I have obviously told them all the ins and outs but aibu to not wanna tell people who have no interest in knowing me or my family other than to discuss school stuff with.
