Quoting Jennybananna:" Everything made my daughter choke as a newborn (except boob) but I was forced to supplement due to low ... [snip!] ... were the only thing she could handle. I think it has something to do with the nipple shape and where the milk comes out."
I never used them but bought the NUK pacifiers... and i'm not breast feeding but will be pumping so thats why I like the drop ins... easy to store... but I bought the Parents Choice drop in brand, they had the nursery pack for 10.00... but I hate the nipples on them... so I was going to try and replace the nipples out lol..
