Rough and tumble

Right now my children look like abuse victims. I swear these two can get more bumps and bruises than any other beings on this planet. We've already discussed Maddie's inability to sit still, which leads to things like the bruise on her cheek, and the scrapes on her legs. There have been more than a few times the kids have bruises down their spines from jumping off things or falling down. Shane's got a bruise on the side of his nose from a fit last night, as well as bumps and bruises from roller skating yesterday. So, tell me the truth... is it just my kids? I'm just waiting for CPS to come knocking, thinking we've been torturing them. *sigh* How do you teach equilibrium?
