Repeated stool after each feed is normal in newborn it's ileocolic reflex but if peri anal area is red and rahses are there than u can apply oint zinc oxide and avoid frequent use of diaper 

Hello, I understand your concern Frequent Loose Stools: It is normal for breastfed newborns to pass small, loose stools multiple times a day—often after feeds or when passing gas. This does not necessarily mean diarrhea, especially if the baby is active, feeding well, and gaining weight. Redness and Rash Around the Anus: The perianal rash is likely due to irritation from frequent stools (especially liquid stools touching the skin repeatedly). This causes a diaper rash or irritant dermatitis. Crying During Stooling or Passing Gas: This is often due to: Local discomfort from the rash Mild colic or gas (very common at this age) Immature digestive system This condition is common and manageable. Continue exclusive breastfeeding and proper diaper care. Most rashes improve with consistent care in a few days.

Hello parent! The perianal excoriation causes pain because of the acidity in the stool. I assume you are breastfeeding and the passage of liquid stool after each feed is due to ileocolic reflex. It tends to settle in next 1-2 months time. You may do a simple stool test to check for lactose intolerance in the baby. If not there, just need to take care of the wound: Please use cotton cloth airy diaper for now. Can even keep the area open as much as you can Clean the area with fingers - the skin will not be corroded further because of rubbing by cloth/ cotton. You can do it carefully over the basin using tepid temperature water. Use simple Zinc oxide cream. Often it is thick and drying. Can alternate it or mix it with Vaseline cream. I will suggest that you add on Oint T bact twice a day to prevent secondary bacterial infection. If a picture was there it would help decide further. But after each cleaning some ointment as all these should be applied to prevent the acidic stool from excoriating the skin further

It's absolutely normal nothing to worry

Greetings it's normal baby passing stools after each feeding.
