Unfortunetly, it seems many parents these days don't feel they need to have two kids at home at once! They send the older one to daycare through mat leave and send the unsick kid to daycare if one is sick...I have had this happen to me many times. They say things like "it is so hard to have two kids home at once when one is sick"...I think these parents just haven't built up the stamina for it because they haven't had to. I can take care of 5 kids at once plus my own and yet many parents can't manage their own two. I don't exclude a healthy child, but I have often thought about this...I hate having the sibling come to daycare when I know the other one has the flu...then it's a waiting game to see if the healthy one will fall ill after infecting us all!
