At our antinatal classes, the MW asked the group if we would give our babies dummies. We were the only ones who said we would. Funnily enough, at the reunion we had, several babies had dummies. lol! The only reason anyone could come up with in that class was that they didn't like the look of 2 yo's with dummies. My DS loves his dummy (he has it for sleep time only now) and it was a life saver when he only wanted to suck constantly, giving himself belly pains from overfeeding. Our reasoning for a dummy was that it would be easier to get rid of than a thumb.
