um well tbh its the same with my cousins - ones 6 ones 9 :S when the younger wants to hold any of mine i just go like *umm yeah okay but sit on the floor so that you cant drop him* but his hands are so small he cant cup mango properly in them!! hehe so then i just like give himtreats that he can feed mango bleess him
but teaching them properly how to hold bogey is a very good idea - it'll get bogey to trust other people more and make the kids really happy lol
just teach them slowly and yeah goodluck Xx
