I would also like to add that as an example, my DS would not eat dinner last night, he picked at it a little and the told me he was all done. It was a meal that he normally loves!!! It might have been his mood, it might have been the day, who knows?? but he nursed, so I have no concerns about him not eating that.
It's hard when people you love and trust give you advice and you want to listen, but at some point you have to make the decision for yourself and your LO. Do your own research and just keep offering your DD a good diet. Your doing good momma, trust your instincts
