Hi about three hours ago my send fell slowly head first off the sette onto rug and his legs went over him. Like a rolly polley but more straight. I just didn't get there in time and feel awful. Hes 16 months old. After he cried for maybe 5 mins then played drank bottle and went to bed. He seemed normal should I worry? Also there is no bump. I feel like watching him sleep all night to check he's ok. :( thanks
