Baby fell

So my daughter (7months) and I are traveling and so we are bunking together and she either rolled or fell of the bed and I just feel horrible like if she had been on the other side of me this wouldn’t happen. I called her doctor and she said she’s probably fine, she definitely gonna have a bruise on her poor head and I can’t help but cry she’s so perfect and she might have fallen cause I was careless about what side she was on the bed, she only calmed down after I got her to nurse but she was so busy crying she didn’t wanna latch, It breaks my heart
