After a month of driving myself crazy, trying different lotions, no lotions, different body soap, otameal baths, different laundry detergent I have finally found relief! I saw my pedi on Thursday and she said that only wash the baby once a week with soap (full body) other than that, just wash her bum with SOME soap and use a luke warm wash cloth and to pat her dry. Stop using the cortizone cream and instead use Eucerin baby eczema relief cream after her bath. I was a bit skeptical about using another cream but I figured I would give it a shot and in not even TWO days it's almost completely gone (with the excepption of a few, small patches). No more big dry patches, red bumps all on her belly, shoulders and legs... it's all gone! I feel so much better.
As with most things, I'm sure it was bothering me more than the baby but I just thought I would share in case anybody else is having a similiar problem. That lotion is a TAD on the expensive side (maybe about $10, but the tube is a decent size) but it is DEFINITELY worth the money.
Thank you all for all of the adivce you have given me, I tried it all, even though it wasn't successful, I understad different things work for different kids but this lotion is definitely worth a try if you're having trouble with stubborn eczema.
