Worst morning ever.

I was trying to burp my increasingly squirmy baby and she shifted, I lost grip, and she face planted off my lap on to the hardwood floor. She landed with a thud, was silent for 2 seconds, then screamed. Now she has a red mark on her head.

I called the ped and they said to just watch her behavior... She is napping now.. I can't believe I did this. I am so mad, worried, and horrified.
