md - we use the tommee tippee ones that have the special supposed anti colic valve to stop that happening lol.. she is a refluxy baby though had to change her formula because she was spewing it all the time now its only every once and a while but i think its still trying to come up but cant because of the thick formula iykwim.. she does have wind but i think its made much worse by the reflux and she does seem to get hiccups all the time where she brings up little bits of milk with them poor thing i do feel bad for her when i am having a sane moment but most the time i am wrapped up in poor me i will crack if she dosn't stop crying iykwim
