With my DD i use the QV range of bath oil, bath wash and moisturiser and have found that quite helpful, have only ever had to use a steroid cream once.
She used to use normal dummies but i found this irritated around her mouth, i now use the Tommee Tippee ones with 2 massive holes on either side to let the air in.

Now she is older i just got a shampoo/body wash from a friend who is a naturopath, she can finally smell like a pretty little girl and it's not irritating her skin.

I'm sure there are lots of people on here with some great ideas on how to help... it's quite common.
