I have a 13 month who is in daycare and I have really have no problems with ... neither does her mother. Yes, I would prefer one of us was home with her(which is financially impossible) and yes, she does get all the little colds ... but her social skills have grown tremendously. She's far more outgoing than the neighbors home raised kid, very resilient and adapting in unfamiliar situations, and certainly doesn't display any of the bratty tantrums. Of course, parenting has plenty to do with it but when I pick her up at the daycare weekday, I always spend at least 15 minutes watching her through the window and just melt when I see her interact with the other children.
As a side note, thanks to our dual-income, her college fund has been growning nicely.
You're doing the right thing. Good for you.
