So I feel like a horrible mother. I left my daughter on the couch all the way against the back while I went to make her a bottle yesterday. never had any issues doing that either. but yesterday she decided she's wanted to follow mommy and rolled herself off the couch and face planted the floor. she screamed I cried. no bruise or anything. she landed face down on the folded up comforter I put under her play mat so I think it scared her more than hurt her but I still feel awful!
