LO has been trying to push up on her hands and knees for a while now but can't seem to do it. I've been helping her move herself to get to that position and once she's there, she lets go and tries to do it again, but just gets frustrated.

The past two days though, when I've put her down for a nap, I've noticed her trying to do it more in her crib than when she's playing with me. Just now, she actually did it, I saw it on the video monitor. She pushed herself up onto her hands and knees and held it for a minute. I'm super proud and I also think it's kind of funny that she seems to want to practice in private.

Has anyone else noticed this?
