Let the Bruising Begin

I know falling down and getting hurt comes with the territory of learning how to walk, but is it normal for a 1 year old to already have a black eye?  We were playing with some wooden blocks so they were littered about the floor.  Beau tripped and fell on one and got a cut under his eye that turned into an ugly bruise. When I change his diaper I'm always seeing bruises on his shins and knees.  And with the way he's always trying to climb on things, I know it's just a matter of time before he gets hurt again.  Oh buddy!
