Hi Jan,
You did not start to early, it is the winter and also he is still at an age that he puts things into his mouth. Talk to the daycare about being more stringent about him washing his hands, get him into a routine, that he washs his hands when he gets to the room and just beofre he leaves atr the end of the day. The first couple months he is getting "innoculated" Aftwards it will be smooth sailing@! happy holidays.
