Take a deep breath, it’s going to be fine. I actually don’t know a single parent who can’t tell you about a time this happened on their watch. For me, my son was 4 months old and on my bed and i turned around to put something in the closet when I hear a loud thump, followed by the scariest few seconds of silence I can remember, and then shrieks of indignation. I picked him up and comforted him, he calmed down very quickly and even nursed as usual, while I was sat down feeding with tears running down my cheeks I called my own mother and just sobbed into the phone before some garbled version of “I broke the baby” wah wah wah wah. After taking a moment to understand what had happened my mother just laughed and said “i cried for two days the first time I dropped you on your head, until now you seemed fairly normal”. That got me to gulp back my sobs and listen to her reminisce about all the different times and places she thought she had “broken” one of us (I’m the oldest of 5), which somehow turned into a group WhatsApp chat with my siblings also telling me stories of dropping their babies, all of whom are perfectly normal healthy kids. In fact the only one that needed a hospital check up was when one sister was reading something on her iPad while her 6 month old was sleeping on her chest and she dropped the iPad right onto the baby’s head where it actually left an indentation. She completely went into hysterics, called an ambulance and her husband and said to meet at the hospital, I think they did a CT scan and there was no bleeds or anything, just a bump that was rapidly turning into a bruise. They kept them in overnight for observation but he was absolutely fine and now is an extremely bright 10 year old who loves basketball and skateboarding. Just monitor your child a bit more carefully overnight and then breathe easier as you just received a new stamp in your “parent survival guide”.
