I already let you in on one of my secrets, but here's another...
Does your child have a yucky diaper rash that doesn't seem to go away with Butt Paste or Desitin? This is what our pediatrician recommended and it worked like magic!
1 oz. Lotrimin [Anti Fungal]
1 oz. Neosporin [Anti Bacterial]
1 oz. A&D Ointment
1 oz. 1% Hydrocortisone Cream [Anti Itch]
Mix together, pat dry, and apply 4 cream times a day. Also air your baby out for 10 minutes, 4 times a day.
Disclaimer: I didn't say this was cheap & I am no physician! :)
