Bunk bed + Head = This

Why does it always seem to happen when Adam is gone? Jack was swinging from the top bunk bed and let go and fell, hitting the back of his head on Brooklin's side board. I heard it all the way in the living room. the knot was huge and thankfully it only bled a little bit. But I was worried. I know I should have trusted God and we did pray over him. Thankfully he was fine and after a good night of sleep it quit hurting by the next day. The pictures do not do it justice.
