M.D.
My 25 weeker had staph infections until she was out of diapers (around 3 1/2 yr old). I don't think she ever had any in her body but always on her diaper area. We tried everything to get rid of it. If she took any kind of medication orally it only made it worse. We went through cases of aquaphor which is the only ointment we could find that worked. Also when I gave her a bath (sometimes a couple of times a day depending on how bad it was) I dumped 1/2 a box of baking soda in the water. It really seemed to help it dry out. It is rough and heartbreaking but she eventually outgrew it. If you wanted to seek a help with Disease control could you ask your pediatrician for a referral? If not, I would call another pediatrician's office for any referrals or check your insurance to see if there is someone on your plan you could check with. Also check with a dermatologist. My derm was the one that suggested we try aquaphor to see if it helped.
