My 10 month old boy is a bit of a cryer and whinger. When i can't calm him down, the dummy mostly can. Is it wrong to use a dummy to keep him happy in this way? He has it quite a lot. I think the negatives are teeth and spec h development. He doesn't have any teeth yet and he babbles quite a lot anyway. I'm just a bit worried about him becoming addicted to it. He doesnt have it for sleep times.
