Baby eating less: is he teething?
Very likely. My daughter's eating habits always took a dip for about a week before her tooth would erupt, with the exception of nursing. She was always a comfort nurser, so she will nurse more frequently when teething. But upon introducing solid foods, her habits would completely change, she would eat much less, and look for crunchier things to snack on in between nursing. I think the crunchy things felt better on her gums.
