Henry vs. the stairs, round 17

Henry's been having an issue with the stairs, lately. He has a permanent bruise on his forehead and a couple of banged up knees. He seems to forget that there's one last pesky step all the time and ends up missing it. And THEN, his dear, sweet older brother decided he was going to sneak up behind Henry and scream and scare Henry today. Didn't bother to think that maybe scaring Henry when he's standing on the landing at the top of the steps might not be such a great idea. So, a flight of stairs later, Henry's got a bigger bruise and a cut chin and scraped up knees. I'm thinking about wrapping him in bubble wrap.
