Pushed up on all 4's

I've been helping Kylie get up on her hands & knees a little lately but she hasn't been interested at ALL. She absolutely hated it. Monday she actually started holding herself up a little. Then she laid on her belly & pushed back up! I was SHOCKED. She did it again tonight! 

Her sitting has improved quite a bit in the past week also. The doctor watched her sit today & said she "passed" but that she needed to lose tone in her back before she could really balance. So apparently he wants her to have crappy posture!
