This new invention, the "Bumbo seat" wasn't around way back when Ben and Lily were babies. It is a little seat made just for little babies who can hold up their heads, but can't sit up yet. It helps them strengthen their cores - very Pilates. Here is Ava having a little Bumbo workout.
Sometimes we sit her in the Bumbo seat on the dining table so she can participate in family dinner. Very cute!
