Hi Diane, It wasn't clear from your post, what or if the mom is doing to "battle thrush" -- and whether the rash is constant or only happens during a nursing session...if it only happens during a session I have to wonder if you're dealing with a contact dermatitis type problem (on the hips from baby in the lap contact) -- any deodorants, diaper creams, mom creams, etc been ruled out? If it's constant and there is oral thrush, what about gentian violet on the the rash? also does she know about treating the family laundry and Daddy as well for a bad thrush outbreak? -- the pacifier may be a site of re exposure -- latex nipples are notorious for harboring yeast, even when washed, I'd suggest throwing away all pacifiers currently in use and boiling any newly bought and used ones every day for at least ten minutes then rinsing them in either baking soda solution or vinegar (WHITE vinager, apple cider vinegar won't be effective) and just to cover all bases throw in a reminder not to give a newly boiled pacifier to the baby -- boiling water can be retained inside the nipple and cause a serious burn... For more info on dealing with stubborn yeast check archives and/or e-mail me, happy to give more details!! good luck, anne p.s. every three hours or so sounds pretty okay for a baby his age with a good supply and good growth, did I misunderstand the "or so" to mean it's very erratic or sometimes much longer between nursings?
