DD is 8 weeks and has started to suck her hands rather a lot, which i am quite happy about as i don't want to give her a dummy, however a few people have now said that hand/thumb sucking is not good but they didn't really say why other than its harder to stop a child thumb sucking than it is to stop a dummy. does anyone have any opinions? i know dummies can interfere with tooth development and i really don't want to give DD a dummy if i can help it. one HV actually encouraged hand sucking while another discouraged it. i personally don't see a problem with it and i thought all babies sucked on their hands! can anyone shed any more light on this? thanks in advance :)
