Am I wrong to use a dummy?

[Jane7]

I've got a very sucky 7 week old baby. I think he may have reflux as he cries a lot after feeds and possets an awful lot as well. I've been brought up to be anti dummies but I bought him one today and he is so happy with it in his mouth, sucking awway. in the evenings, before now he's wanted to nurse all night to soothe himself with sucking, now he's got a dummy i'm pleased that he can suck and be soothed without taking in so much milk, but i'm also nervous about dummy use. i don't want to give him the dummy when he might be hungry. It's just that i don't think he sucks because he's hungry in the evening but because he wants comfort and his reflux causes him discomfort. Anyone got any advice for me. I'd love to know people's thoughts on dummies. Will he become reliant on a dummy to soothe himself if I start using one now?

Ds3 never had a dummy, partially because he was prem and in SCBU where he was given bottles of EBM and I wanted him to breastfeed as much as possible when he came out as I felt his breastfeeding start wasn't great. But he later developed an aversion to bottles which was unhelpful as I had to return to work. I did wonder afterwards whether the dummy would have helped him to take a bottle, as he would have been familiar with sucking on something other than my breast!
My other 3 boys have used dummies and all breastfed successfully ( and took a bottle!!!) so my own experience would suggest the dummy was a good thing!
