Do kids carry infections from daycare? My kid remains fine but as soon as I start his daycare he gets chest infection.

Your child is in protected environment at home just like a fish in aquarium. There are no foreign elements interfering. Most of parents complain that kids get more ill while in daycare or school. Definitely kids get more prone to sickness which is contagious in nature and carried into by touching or sharing of items like toys or utensils. Please make sure your kid gets nice clean environment in daycare. And always wash your child's hands properly this removes 75% of infections.
