Since about 6 weeks old, LO has not been a fan of the bottle. She used to be totally fine with them and then suddenly she decided they were offensive. Now that I'm going back to work in January, we've been working more with her on the bottles. We're trying the latex nipples (Nuk and Playtex) and she seems to like them better, but it is taking her FOREVER to drink even an ounce. Sometimes I think she gets frustrated because the nipples are so slow and then starts crying. I did get the fast flow Playtex ones (still pretty slow) and the medium flow Gerber First Essentials (too fast). Anybody have experience with this? Is this something she'll get better with the more we give her the bottle?
