My 13 month old suddenly fell off from the changing table and she landed on the floor on the back of her head. The sound was hard like "piak" sound and he cried on off. He fell asleep shortly after. What should I look out for? Should I bring him to A&E now?

once your baby wakes up i would suggest try playing with baby. if he feels normal, not cranky and does not vomit, then everything should be fine. for any other such incidents, avoid letting baby fall to sleep immediately after a fall, as it can help you notice any signs that may require you to take baby to the doc. if you feel that your baby is lethargic, is not communicating as well or is pukish, go to the doc immediately
