Well I'm not conifdent in saying Ruth is sitting solo just yet, she's very close! I've sat her down a few times now and she'll hold herself up for short periods of time!
I can't let her sit without being there to catch her or help yet, but we're very close.
Sometimes I think she wants to and she gets mad laying down and rolling around. She wants to be up seeing more of what's going on and playing with her siblings and us!
