We've had similar issues. Sam's in day care one day per week. I try to feed him stuff with lots of garlic (my immune system has been pretty run down too) so we've been eating lots of spag bol lately! We use brauers recovery tonic when he has bugs, and that does seem to help him get over them a little faster. The other thing I've taken to doing - thoroughly cleaning his face and hands as soon as possible after daycare or when he's spent time with other kids. I've even taken to going over him thoroughly with the wipes as soon as we get in the car - when we got home just wasn't soon enough!
