What is that on the couch???

I came out of the shower this morning, and after getting dressed, went into the living room to see what mischief Ethan had gotten in to. Immediately my eyes were drawn to something bright red all over the couch. The markers are on a high shelf, so I racked my brain for what he could have smeared all over the couch that's so red. Then it hit me! BLOOD! A quick check and I discovered Ethan's first three toes on his right foot covered in it. Asking what happened was fruitless, so I began cleaning his foot to find the source. It took some looking. Apparently, all this blood came from a tiny, tiny scrape on the bottom of his second toe. Of course, while I was finding the little bandaids and bacitracin he ran all over the house leaving little spots of blood on carpeting, clothes on the floor, and again, the couch. When I finally found the bandaids (they'd fallen behind the medicine chest), I had to clean off his bloody foot again. Now he is complaining about the bandaid (he hates them), but I'm not letting him take it off until the bleeding has stopped. I already have enough to clean. (Maybe we'll go to IKEA and buy another slipcover for the couch. I don't think it's worth attempting to clean.)

Update : Thanks to Beth's mom for the heads up that peroxide gets out blood. I replaced the couch cover anyway b/c it was nearly destroyed pre-blood and so shrunken from many, many washes that it was ripping at the seams. But I'm totally going to use peroxide on those carpet spots. Thanks!!
