Baby fell off bed about 4 times different occasions

My 6 month old daughter has been left on the bed by my husband 4 times different days and fallen off the bed. I’m so worried this is going to change her health I’ve told him numerous times to not keep his eyes off her and yet he still does it. The bed is fairly low but this doesn’t change my concern. After every fall she’s been perfectly fine and back to acting her normal self, but I’m scared that it’s happened way too many times in a short period of time.
