It is very common for babies to bump and bruise while jumping up and down in the house, so don’t panic too much. If the skin surface is only slightly scraped a little skin, there is a small amount of bleeding, you can use a cotton swab dipped in an appropriate amount of iodophor topical application, twice a day disinfection. If you have red salve on hand, after the iodophor is applied dry then apply red salve for the second time, red salve has the role of promoting incision scabbing and healing, which is also a good choice. Nowadays, pharmacies basically have Bactrim spray, whose main ingredient is benzalkonium chloride solution, which is quite disinfecting and convenient. After spraying, the skin surface can be covered with a band-aid to prevent the baby from scratching the incision when it is almost healed, leading to aggravation of the condition.
