K.P.
One thing I have noticed with most kids is that they act differently with different people or at different places. My almost 3 year old daughter chatters all the time when she is with with us. After the first 3 weeks of daycare, my Aunt picked her up, the next day when I went in the teacher said "Wow! I didn't know Erin could talk. She talks really well." Apparently my daughter and aunt had quite a conversation while the teacher stood there amazed. Have you ever noticed a child that is behaving until he sees his mother or the other way around? Maybe he just doesn't like daycare. You can pretty much bet he doesn't get as much attention there as he does from you. Maybe he is just adjusting to playing with other kids his age. Erin is the same way when it comes to eating. She will eat what I give her because I know what she likes and I give her those things (to a certain extent) but I can't imagine daycare food tasting any better than that of a school or hospital and I know you remember what hospital food tastes like. Just give it time. He will come around. If he doesn't you could always try another daycare or try to find an individual to take care of him. Hope it helps!
