In the past 10 months Ben has smashed his finger in a car door and had the fingernail fall off, had all of his fingers caught in a car door (luckily that time he was holding a corndog and it got the brunt of the damage.) He then slamed his thumb in the car door, then a few weeks later he slamed it in the sliding door. It was looking a little red and it was pretty tender, he then was playing with a truck and it flipped back and caught the same thumb at the cuticle. It turned BLACK and just this last week the new nail grew in and the old one fell off. Poor Ben:( Tough kid though!! We'll see how long we can go WITHOUT losing another fingernail!
