10.5 month old baby is constantly falling and banging/hitting his head now that he's started to crawl. Yesterday he was banging on the radiator and fell forward and hit his head, today he was kneeling to the sofa and fell and face planted the floor and has now got this other mark. I feel so guilty it’s because we’ve got hard floors in the living room and laminate throughout the rest of the downstairs but I don’t know how I can help it other than wrapping him in bubble wrap. I have a large mat in the living room for him to play on but he's always venturing off. Is this normal or should I maybe get him checked out? He screamed when it happened and it took a little while to calm him but he's happy as Larry now, but has these 2 marks which look quite sore.
