BTW... when my friends bring their children around DS and know that their child has a cold etc... and still let them touch on DS. I get very upset and i think they're being selfish too!!
DS is only 5 months and I know he will get sick and he already has been but even I wash my hands everytime I pick him up. Also when he's sick I do warn other mom's in our play group because I would'nt want to get their child sick either. That just common courtesy.
