Does your baby bump his head ALL the time?!

Li

My 8 month old boy seems to be going through a stage of falling and smacking his head no matter how much I watch him. Now he can stand he’s started jumping around in bed and tonight hit his forehead on the bars and has a blue lump 😭 he cried for a few mins but he was fine again and went to bed like normal. I’ve got bumpers but he still manages to find any hard spot he can! I’m worried he’s actually going to damage himself or am I just being OTT and all kids have bumps and bruises at this stage?
