My son is currently 9 months old. Sometimes when he is in my arms, or when we are playing and he can reach them, he tries to grab my glasses. I know that he is just curious. He is just in that stage that he is exploring everything and I understand, welcome and foster that, but I'm also concerned that one day he might drop them or break the frame as he is pulling them from my face (or a relative's face).
Currently I have an older set that I use at home when I'm with him, but that doesn't mean that I wouldn't care if these are broken. I don't use contact lenses. I have in the past, but I work in front of the computer and I don't find them practical for that (and I wouldn't want to switch to contact as I get home). Besides, his grandparents and one of his uncles uses eyeglasses too, so I would rather find a way to teach him that people's eyeglasses are "off limits" instead of toys.
Is there a good way to teach him, at this age, not to grab people's glasses without discouraging curiosity?
