I felt like the worst mother ever!

I had dinner baking in the oven and never thought twice about Bjorn getting hurt. I heard him cry but didn't put two and two together until Nathan saw his fingers when he came home. He had opened the bottom drawer of the oven and put his fingers up into the stove and burned two fingers! He had 2 large blisters poor baby! I felt awful and a terrible momma even though it was an accident!
