My son fell off the couch, please help!?

first watch the affected area carefully for any abrasion or swelling .if nothing is there and baby is fine then no need to worry.if there is any abrasion then take aseptic precaution like applying dettol,if there is swelling you have to be careful and medical attention is needed.give special precaution if there is head injury.but dont worry my seven month baby falls frequently while trying to stand up
