LO is 7 months old, and until recently she was taking 3 oz of breast milk about every 2 1/2-3 hours (she's EBF when I'm home). She also usually takes around 3.5 oz of purees 2 times a day. She started eating less of the purees a week or so ago, and seems to be losing interest in them. She was still nursing just fine so I wasn't concerned. Well now, she's been leaving an oz or more in her bottles, and doesn't want to finish them. Should I be worried? Has this happened with anyone else?
