What to put on babys neck folds ,??? (How to keep clean ??)

I put powder my son never had this problem lol but my daughter does yeah it does stink wipe it then dry it then powder

There's not much you can do other than use wipes throughout the day or a washcloth..especially after each feeding!

Just use wet wipes throughout the day especially after feedings. Milk doesn't smell great when it's been in a baby's neck rolls for several hours 😂
