My 9 months old baby just had a bang on the back of her head against the floor. She was playing on the floor when she lay backwards and knock the back of her head on the marble flooring. Anything to take note?

Firstly, check for bumps. Rub some ice pack on her bump area immediately in future if she falls or injures. It will ease off the swell. Make sure there are no swelling. Take note of any decrease in feeding other than vomiting. Some children develop fever due to fright. Watch her movements as well to see if she has any slow or delayed movements. Also, ensure that she doesn't cry uncontrollably as she is only 9 mths old. All these are tell tale signs that she is uncomfortable. You might have to bring her to hospital for further observations if you sense something is not right.
