Feel like a failure

My little baby girl fell off the couch today and I feel like the most awful parent. We were just watching a kids show she loves, I sneezed and she launched herself over the arm. I didn’t even realized what happened until I heard a thud on the floor. She started crying, I comforted her and she calmed down a bit. Of course, immediate panic set in and the pediatrician isn’t open today. I talked to my MIL, who’s raised 6 kids, fosters babies and has 6 grandkids, so she knows her stuff. Thank god, my little girl seems fine, not even a bump, even tho I’m not really sure how she even landed. I know accidents happen but I feel like a shitbag nonetheless. I just needed to vent to people who understand what this crazy parenting life is like 😣
