Hi there, my youngest is three next month - dx with IPT in April (nose bleeds, major bruising, petechiae and a count of 2) and in July was dx with autism. Lots of fun. Yes, I understand your predicament all too well. He's the youngest of five children, four boys (2,4,11,14), one girl (

, all very energetic and love to climb high, run fast, wrestle etc and have no fear. He's already had four hospital admissions for infusions - these being the hardest for him because he simply DOESN'T understand in any form. He has to be sedated before they can put the needle in for the iv. He was so upset while still sedated that he broke out in petechase while they were putting the iv in. Had twice as many dots on him afterwards. I simply can't explain in even the simplest terms what he's not allowed to do so the only thing I can do is not leave him alone - ever. He just gets no, Ethan...means things don't get done around the house because he wants to play outside for two hours. So there I am. He could climb up onto the tv cabinet, chair, slip on anything, the kids beds etc - it's too dangerous at that young age with a low count. I get looks like, have you abuse your child or what?! because of the bruising. Taking a letter around with you is actually a good idea - hadn't thought of that wildrose.
How much does your son understand? Does he respond to 'no'? He may still do what he knows he's not allowed to do, but does he KNOW he'll get a response from you? Ethan will look around at you and wait for the 'no' but it doesn't stop him - kinda like a game. It's difficult, I know, but all you can really do it try your best. Saftey proof the house as much as you can. My boy has the little brusies like your son and has also had ones the size of a fist. Thing is the longer he's had ITP, the less symptoms he's got when his count is dropping. He looks fine apart from a few brusies, smaller ones, no petechiae that you can really see and it's at 5. Can't tell anymore by his symptoms. I've seen them come up when I KNOW he hasn't hit himself in any fashion - say when he'd had a quiet day. I agree with wildrose about the brusies. We're in Australia where I feel the treatment has been excellent. I understand that it's more difficult in the UK? Perhaps you can tighten the pedals of his bike or some parts of his bike somehow so that it rubs together more and is slower? Sounds dumb, but you know what I mean. More friction could it go slower. Definately, a helmet
