Uh-oh, we're in trouble!

Little Miss Sasha has figured out how to get on all fours! Yikes! She did this first on Tuesday, I totally thought it was a fluke. But nope, she's been doing it since then. At first, she'd stand like that for a split second and then flop right back on her tummy. Well, today, she started rocking back and forth! I'm scared! I told Z that babyproofing and mattress lowering are happening tonight. Gosh, I'm not ready for this yet...
