My DD is almost 6 months old and has quite eagerly been taking puree for the last 3 weeks, once a day. The last two days she has refused any puree, even the familar ones which she liked. She takes a little bit and then starts gagging on it, at the same time she has started waking 3 times a night, where previously she has been an excellent sleeper (12 hours a night from 12 weeks with a dream feed at 10pm. Am I doing something wrong or is this just normal?
