Did your younger child get sick all the time when they started daycare, even if they already caught a lot from their older sibling's first year of child care?

We all suffered a constant stream of illness this year, my 3-year old's first year in preschool. I felt so bad for the baby.

Well now I'm looking at putting the baby into daycare. Is it going to be way, way better since she caught so much this year? Or should I keep my expectations low? If I pay for full-time daycare and hardly get to use it, I just might die.
