I ask this because sometimes my son (who turns 11 months old today) will rip my glasses off accidentally when we're down on the floor playing and he gets a bit boisterous or is reaching for my face/shoulder, etc. I know he isn't doing it on purpose, but if I tell him "no, don't pull my glasses off" he either hides his face in his "shy boy" pose or - today - lay down with his face on his hands and wouldn't look at me.
How much does he understand? How can I tell him not to do something if he is going to crumple in a heap? It's just from a safety point of view - I got a finger in the eye while he was ripping my glasses off today, I'm trying to make sure he knows it's serious and not a game.
I gave him a cuddle when I saw he was hiding his face from me and several kisses and we played with his pegmen and he was fine, but the incident worried me. He is usually a very sociable, happy boy.
