I have a 2 1/2 year old son and I know he can talk when he wants to but recently he has stopped using his words and just whines and cries all the time I ask him what he wants and sometimes he will tell me other wise I'm left to guess what he wants it's very frustrating I am 37 weeks pregnant and the more pregnant I get the more whiny crying fits he seems to have
Re: 2 1/2 year old stopped talking
Agree with PP but don't only focus on how much help you'll need all the time. Also focus on how special he is and how much you love him and how he'll always be your baby.
Also, I wouldn't give him what he wants until he speaks, if you know he can. "Oh, you want that cup. Can you ask for it? I'll give it to you as soon as you ask for it" and then seriously don't hand it over.
This is what I do. When I was hugely pregnant and baby stuff started piling up in the house, DS acted out a little bit, and he did the whiny/crying thing without using his words. We did exactly the aforementioned thing, and we still continue it when he whines.
And call your pedi too. It can't hurt to have it checked.
[unless he is legit sick. If he is, whining is not "okay", but it's more tolerated.]
