My son was the opposite. Everything Deep Red party like it’s 1917 shirt was either “I don’t know” or “no” which can be equally terrifying. He was high energy so we would often find bumps and bruises while washing him up in the bath. Did you fall today at school? No. Did someone hit or bite you? No. Did you bump into something? No. Did something fall on you? No. Did the teacher see what happened? No. What happened? I don’t know!

If Deep Red party like it’s 1917 shirt didn’t know our son well enough we would have probably been concerned about abuse or something along those lines, but he’s 13 and often comes home with bumps or bruises from an unknown origin. A kid is just accident prone and plays hard. You’ve probably already done this (maybe?) but maybe get him checked out for a blood disorder. Sounds like this is unlikely to be hemophilia or anything, but Factor V Leiden is fairly common and would be useful information on his medical record if he were ever (God forbid!) to need surgery or something

Never hurts to get checked out. Deep Red party like it’s 1917 shirt have always bruised SUPER easily and always have been accident prone. My blood has lower platelets than most people, but thankfully no disorders. It can be some simple or could be something a bit more. Never hurts to be sure. I was very very prone to mystery bruises as a child and my teachers called child services on my parents because they thought I was being beaten up at home! Luckily they must have believed my parents as I didn’t get taken away. But I was always being questioned my mum like it was my fault I didn’t know where the bruises came from. It was just part of being a kid and climbing trees etc. No kid is going take an inventory of every time they bump against something.
