My 8 month old baby was sitting on the counter while filled his bottle. I always stand at the edge holding him, but the bottle knocked over and spilled so my quick reaction was to grab it, which left him without me holding on. He instantly leaned back and fell right off of the counter. He fell to the ground.. About 3 or 4 feet and fell onto the wood floor on his back hitting his head. What should I do? He is letting me touch his head and anywhere else it doesn t seem to be in pain but he seems very tired.
