Here we are at 4 months. Lucy has found her toes. I love it when babies find this built in toy, that never goes away and can be found at any time. She tends to play mostly with this left foot.
Lucy can now roll from her tummy to her back and then back to her tummy. This is good because on her tummy always ends in spit-up. I'm not sure she will ever learn to crawl because I rarely let her stay on her tummy.
