A., both my kids were also preemies, but I am a stay at home mom and I didnt have a whole lot of problems other than colds, On the other hand, because my kids dont go to daycare, as soon as Devin my oldest hit pre-k he got everything and anything that went around. So we were constantly taking him to the doctor. I have heard that when kids are in daycare, they do get more illnesses. But one way to look at it, by the time they are in school, they should be over it. So this may not help right now, but it will get better for you. I had the same problem just opposite timming. Sorry this isnt much help, but you are not alone. Have you thought about taking them to a babysitter instead of a daycare with less kids. This might help out a little. Just an idea. Good Luck to you.
