Baby accident

On Friday morning I was changing my 8 month old on her changing table as normal and my 20 month old was running about the bathroom adding to distraction. My 8 month old began peeing as soon as a I took her nappy off so I thought to myself I may aswell bath them both now as they needed one that day anyways. So, my 8 month old was playing with a packet of wipes and the bath is right next to the changing table. I quickly turned the bath on and I mean it was literally a 2 second job and like right beside the table and when I was turning myself back to the table my poor baby girl rolled off the table 😭😭😭 her cry honestly haunts me. I quickly lifted her up and screamed for my parents as they were in the house. They came straight away and my mummy phoned the hospital (phone first service) while I consoled her. I brought her to the hospital to get checked over and she is absolutely fine other than a couple bruises to the face but I honestly fail like the worst person in the world. She was back to her happy self around 15 minutes after the fall but I am honestly horrified. Such a big drop from the changing table and on to tiles 😭😭 has anyone else had anything similar happen to them and feel like the worst mummy in the world?? They deserve better than me??
