The most asked question, again, how much is your LO talking? At ds 18 month visit, the pediatrician was concerned about his talking. He said to call back in a month if he wasn't talking much more. He wasn't, but ped wasn't concerned because he uses phrases like " thank you" "I did it.".
He still doesn't talk a lot. I know you shouldn't compare, but dd was having full blown conversations at this point.
We see the ped. In 2 weeks for his well visit. We are seeing a different doctor. I think ours brushes stuff off too easily. IE ds dropped percentiles in height, he says his allergies are intolerances.
Re: Talking
That said go with your mommy gut. If you think something is wrong, I say go for an evaluation. If something is wrong, you can address it sooner rather than later. If not, at least you can set your mind at ease!
