My daughter is really interested in food it's become insane! She will try and pull our plates or bowls towards her, stares as we eat or cook, and when I let her taste (letting it touch her tongue) she instantly bites down. She's only 4 months old ad we see her doctor Tuesday so I plan on bringing it up. Has anyone else dealt with this? What should I expect?
