I'm a bad mother... I put the baby to sleep, we're sleeping together, I went to the bathroom, while I was walking the baby fell off the bed, he lay on the floor with his head down. He was crying, probably from fright, I looked at him externally and there were no visible injuries, he didn't vomit, I calmed him down and put him to sleep. Tomorrow in the morning we go to the hospital. Who else has their children falling? What are the consequences? What tests need to be done, what doctors should you see? (almost 11 months old baby)
