Enter Challenge #2... any toys I put on the floor for her to play with she inevitably pushes away from herself and then falls over trying to get to them.
I accidentally stumbled across this fantastic idea.
Nice, huh? It keeps her sitting up and keeps her toys right within her reach! It won't last for much longer but it works for me right now.
Caution: I have now learned that if she's barefoot her toes can kind of get caught in the holes so a blanket over the holes is helpful in that situation.
