For those of you breastfeeding mothers, what kind of bottles do you use when you bottle feed? At first my daughter would take only bottle so I didn't have this problem, but now that she is breastfeeding she doesn't want the bottle anymore. She just feels the bottle nipple with her tongue and then spits it out. I only want to use it when we are out in public, but it's so difficult because she won't take a bottle. I have tried the Avent, Playtex drop ins, BornFree, MAM, ThinkBaby, Playtex Advanced, Nuk, and some other bottles I can't remember, but she won't take them. Any suggestions? Could it be the milk?
