My 5 months baby just fall down from the bed. He cry so loud and I pick him up. He looks fine now, can play and laugh. What should I look out for? Vomiting?

Yes, vomiting. Also look for bumps, cuts, bruises. Firmly grip limbs and watch reaction if baby cries in pain, to check if any broken bones. Don't let him sleep, in case of concussion. My toddler fell out of her crib when she was 8-9 months old, but she was okay. I think an angel was watching over her. I can imagine how you're feeling. I felt like ice all over my body!
