Dd has met her milestones so far (rolling back and forth included) and is working on walking by herself. She uses the furniture to walk, her walker like a pro zooming everywhere, but crawling is still her go to get around method. Well the last week we’ve noticed that she hasn’t been rolling over after Ive change her diaper on the floor and she’s left laying on her back. In her bed or sofa .... no problem rolling back and forth. Just seems like on the floor or hard surface she’s having a issue and it’s making her upset she just arches her back. We will give more floor time on her back to help strengthen her muscles. her head is in the 100% and wondering if the size isn’t helping her. Just checking in with other moms wondering if they’ve also had this happen or what your thoughts are.
