I use the Breastflow bottles, and I understand what you mean by milk getting stuck. Well, it happened with me too, and I would just press the tabs till all the milk flowed back into the bottle and give it to DS again. I would make sure that I would first let that remaining milk go directly into the inner (it's blue in our case) nipple and then let him have it, that way there's less of a chance that the milk gets in between again. But it does keep happening and I just repeat the process. I'm now giving DS formula, so I don't care much about throwing away that little bit, but did care when I was giving him expressed milk. Unfortunaely BF didn't work for us, so I can't say if a differnt bottle is better. But I know other BFing moms who use other bottles (Born Free, Vent air etc). Maybe you could try those too. I was tyring to get DS to latch and thought these bottles might help. They didn't (figured DS knew how to, but just didn't want to - wish I knew why ). But it so happened that he just got used to these bottles.
