My baby got hit on her back head on a steel cot it was kind of forcely as she bent back when I was feeding her food. I found some blood on the head and as I pressed the area it cleared out and no further bleeding. She cried continuously for nearly 20 minutes and then started playing. She's sleeping after 2 hours of the hit now. I am so much worried as the cot is really strong steel and even few centimetres distant hit would pain much. Experts pls guide.
