My baby daughter Isabel has a bottomless appetite, it seems. Hard to know for sure since she only started eating solid foods two months ago. She prefers to feed herself, double-fisting crackers or fruit (strawberries are her favorite, though she’s recently gotten into Asian pears). That she only has two bottom teeth doesn’t deter her. A common occurrence lately is she’ll feed herself out at restaurant, and then half an hour later I’ll notice her taking some food from her fist and shoving it into her mouth. She will have had clung to that french fry or pretzel stick long past meal time, saving it for later, to eat in the cab. Perhaps it’s a primal survival hack.
