Kaiya's previous attempts at sitting consisted of her folding in half, like a sandwich (what Aunty Stacie in Portland likes to describe it). However, in the recent days, she's been doing fabulous at sitting straight up like a big girl. Of course, we're there to spot her...but we also let her fall over sometimes onto the carpet or pillows.
We're now working on her getting from her belly to a sitting position all on her own. We're anticipating that might take a while, though.
