A.,
I'm so sorry to hear about your loss. I have a couple of comments. First, that is a huge change in your children's lifes and I'm not surprised if she is acting more withdrawn or different. Second, my little brother hardly talked at all until he was 3 and went to pre-school. I pretty much talked for him and he had no need to talk more. He is fine now. Third, the daycare workers probably meant well-- and might have been in line to say she isn't talking or interacting at the normal level for her age, but they certainly can not diagnosis such a disorder. I would talk to your pediatrician and follow his or her advice. If you feel your daughter should be talking more or more social-- try a class with other kids. I have a feeling she will be just fine.
Good luck. You will be in my thoughts.
