DS is 3 and since he was a baby he has sucked 2 of his fingers. He does it when he's tired mostly or when he's relaxing. It's a comfort thing, I know. It's got to the point now though that he has 2 'holes' on his fingers cos he sucks that hard and when he's in bed we can hear him over the tv downstairs! I do worry that it's affecting his speech (he doesn't always take his fingers out to speak) but his nursery say his speech is at 'normal' level and nothing to worry about. Should I be discouraging it? I'm thinking it could make him do it more if I try to stop him. If we're sat reading or watching tv I hold his hand so he can't do it but he slyly pulls it away! He seems to get a lot of colds and I don't think sucking his fingers is helping, germ wise. Any advice?
