I can't figure out how to teach my 2 year old that his new baby brother is fragile.

I have a two-and-a-half-year-old son who is very kind-hearted and wants to help with the baby. if I turn my back for just a minute sometimes I find a blanket over the baby's face and then I rush over to take it off and my two-year-old says that he thought the baby was cold. He only seems to make little mistakes when he's trying to help but I don't know how to explain to him that he could smother the baby. My 2 year old is definitely not ready for the death talk.Any thoughts about how I can communicate this to my 2 year old would be great. My two-and-a-half-year-old is very smart and is already using six and seven word sentences so I think I could get him to understand if I just knew the right way of doing it without getting him too upset. via /r/Parenting http://ift.tt/2t3rThR
