Tapestry,
I'm the second poster and realized that I did not give my ds's history. He started at age 5 months and was relatively healthy at that point. IT was a large daycare center. I really liked the center itself. However, the very next week my ds had his first ear infection and was literally sick non-stop until we dropped him out at the advice of his drs 3 months later. During that short 3 months, he had numerous ear infections, stomach bugs, pink eye, 2 sinus infections, spent nearly the whole time wheezing, had RSV and pneumonia. We were spending $125/wk for daycare and he was *maybe* going 2 days average per week because he was too sick. After the RSV and first pneumonia, we dropped him out and he stayed with my mom. He did have an older brother (non-cf) and cousins that he was exposed to. 8 months later, when I was nearing my due date for our dd, we started him in a small in-home daycare (my mother was 70 and couldn't watch 2 small children). His lungs had finally healed by that time and the only illnesses he'd had in the preceeding few months were ear infections. Within a month, the lung infections started again, along with more ear infections and sinus infections. However, they were not as frequent or as severe in the smaller setting as they were in the larger setting. It worked ok. At 2-1/2, he started in another daycare center. It was smaller than the original center (approx 50 children total). Now, at 6-1/2, he's in public school. He still has a lot of lung/sinus problems, esp between Aug (ragweed/mold season here) through the winter months, but he's healthier than he was when he was little. In all honesty, I very much wish I could have stayed home with him those first 3 years, partly because I have no doubt that daycare contributed to his poor health in those early years (as evidenced by the fact that he was relatively healthy before he started daycare), and partly for the reasons the first poster cited. But, in the end, he's a relatively healthy, happy, outgoing child. In the end, it is YOUR decision and yours alone to make. Go with your heart and what feels best for your family, not what any of us say. Good luck!
