My daughter is 14 weeks old and over the last few weeks has become increasingly difficult to feed during the second half of her bottle. She guzzles down the first 2-3 oz no problem, however, once I have winded her half way through she will fuss over the remaining 3oz, playing with/chewing the teat, pushing it out with her tongue, turning her head and wriggling in my lap. She is definitely still hungry as she eventually takes it, but it can take up to 50 mins for her to finish a full bottle. She is on Doc Browns level 2 teats which I think are fine for her as the level 3 are too fast. Has anyone had a similar experience?....I am at my wits end here and dreading feeding times!!
