Ds is 4 now. He's absolutely fine, chatty, happy, in no way behind for his age.
We went to see PIL today and ds was chatting away and FIL said to MIL "he's ok now isn't he, we were worried he was backwards." I said "what do you mean?" And FIL said that when ds was about two and wasn't saying as much as their great niece who was a similar age at the time they'd thought ds was "slow" and "backwards."
Aibu to think what is wrong with these people?! There is clearly not, nor has there even a vague delay with ds and even if there had been quite frankly the terms "backwards" and "slow" get my back up!
