Self-cleaning toddlers

Well, LittleBit surprised me yesterday. After a couple months of very laid-back "do you want to sit on the potty chair?" (we haven't pushed, because she's had constipation issues for so long, and hasn't seemed interested).......

Yesterday morning, when she woke up, she told me "no more diapers, I want panties". So I put her in panties, thanking the powers that be for hardwood floors, since she would surely be soiling them any minute.

She has been using the potty and staying dry ever since. Yep, LittleBit potty-trained herself. All on her own. Not too shabby. Her sister was trained at 2 1/2 as well, but it had been after several months of trying.

Can it really be this simple???
