My 27 month old son just fell down a flight of hardwood stairs and I found him on his back. He was crying and his nose is scraped and raw near the nostrils with slight bleeding for around 10 minutes coming from within his nose. Unfortunately he also is just getting over the flu so his nose has been back and forth with congestion and runny. He was extremely clingy for about 1-2 hrs following this, but seemed to be ok. I did not witness the fall but it definitely seems like his nose and forehead came in contact with the stairs. Should I be worried about the nosebleed? With his cold I couldn't tell if it was mucus or clear fluid mixed with blood.
