Good night! Here's another time my son fell out of bed and now he has a red nose at the tip(( I'm really worried because it's not the first time he falls. I was putting off buying bumpers, putting off, now I ordered them at night. I wanted to ask how many times your children have fallen out of bed until 8-9 months old, up to a year?? What research is better to do?? NCSG? MRI?
