My youngest (3.5) DS has always been really good with food - will eat pretty much anything you put in front of him, lovely table manners etc. I've started minding another boy (4) twice a week who is lovely they get on brilliantly but he is a very fussy eater & it's started to rub off on DS. Little things like using his hands more to eat, announcing things he's previously loved as "yucky" and generally announcing "I don't like that" to pretty much everything I offer (my reply of "yes you do now eat up" still works but I wonder how long for)
Any tactics on stopping mindees bad habits rubbing off on your own children in particular poor eating?
