roll baby, roll

i put lilli on her side and was reading blogs--when i looked back, lilli had rolled onto her belly and was scooting herself forward! she then rolled back to her side and onto her back!! so proud of her!!! we'll see if it was a 1 time thing, or if she'll keep doing it! she also scoots around on her back while in her crib--she's never where we leave her!
