My doctor reccommended CORTAID OINTMENT (not cream) for my kids when they were only a few months old. It worked great for all of them!!
If it is eczema, the cortaid ointment will work wonders. If that doesn’t work it may be a fungal rash. Babies get them in their creases – places that sometimes stay a little wet after a bath. A little monitstat will clear it up if that’s what it is.
My doctor said both products are fine, use a thin layer twice per day. If it gets worse with the cortaid, it’s probably fungal; switch to the monistat, and use the monistat for a few days after it clears up to prevent it from coming back.
Hope that helps
