First Major Boo-Boo

Max had his first major boo-boo tonight. He was running around being silly when he slipped and fell into the bottom of the computer chair. He has a little puncture and a knot instantly appeared. It looks terrible! It was almost 10 o'clock when it happened, so it's kinda hard to keep him awake now like I've heard you are supposed to do with a head injury. Here is a picture I took right after it happened. Is this typical for a goose egg bump? This is our first time dealing with something like this. It looks so bad in real life.

I kept him awake for an hour, I'll try to check him throughout the night. Poor little guy!
