Baby fell off the bed :-(

Ginny • Expecting Baby #1 on 3/13/15!
I have her crib mattress on the floor and normally once I put her down she doesn't move for the night but DH and his friends are playing games outside the bedroom and being loud which caused her to squirm while she was sleeping. Next thing I know I hear a thunk and she's fallen off her mattress onto the floor. I'm mad at myself for not putting her further into the bed but I'm also really pissed at the guys for being loud. They know there's a baby sleeping here!!!
