I'm looking for a bottle slow enough for my 2wk old. I've already tried; Comotomo, Mam, playtex ventaire, standard evenflo glass bottle, tommee tippee, avent natural, even tried those Enfamil 2oz nursette bottles, all with their "slow" nipples and my babe just chokes on them all and as she's swallowing spits a bunch of breastmilk out through the sides. Apart from her suffering she's going through so much breastmilk since she's leaking through the sides of her mouth and don't have an accurate reading on how much she's eating. Help anyone?
