Just as I was doing activities that could help Emilia to crawl {or get ready to crawl), she suddenly showed an interest in rolling from tummy to back, which she had done only a few times before. Past few days she tried many times to roll to her back with only several successes and finally it must have clicked on her, because this morning she has been rolling all around on the floor, back to tummy and tummy to back. She is now able to move to different spots on the playmat, and off the playmat sometimes, to get closer to her toys.
