Please tell me I’m not the only mom...

My 10 month old fell head first off the couch today and I was literally right there grabbing his toy he threw.. when he decided to lean over as well and down he went. I tried to grab him but was only able to catch his onesie so he ended up still hitting the top of his head. And of course now I feel like the worst mom ever and am hyper vigilant about his every move and whether he is showing signs of any head trauma. Idk why but when this happens I always feel like I’m the only one whose baby has fallen from anything and beat myself up about it for a few days. This is the second time he has fallen so I’m still not used to the fact that it can happen.
