So my in laws are staying with us for about a month, which is great! I love them, we’re a happy family and get along like friends.

The advice I’m seeking is about putting hands in my 5 month olds mouth! She’s of course big on everything going to her mouth these days but it just gives me the ick to look over and see her sitting there chewing away on someones fingers. Am I being extra or is this reasonable that I’m icked out and want to set a boundary? If so any advice on how to set that boundary without making them feel any type of way?? (It’s their first grand baby and only second time meeting her so i would rather bite my tongue than make them feel insecure but a month is a long time lol!!)
