Poor love...not to make you worry but I actually got the PUPP rash on day 9 AFTER Darcy was born (my due date). I itch all the time with psoriasis but that nearly drove me spare, so you have my total sympathy.

Have you tried oatmeal baths? (put some oats in a small muslin bag and run under the tap to fill the bath). I also take flaxseed oil, check with the chemist of course but this helps with my irritation.

Good luck tomorrow!
