My second child had eczema and I learned that there is no magic bullet when it comes to dealing with eczema. What works for one person may not work for another and that’s the really frustrating part – having to go through the process of finding relief when you just want to make it better fast so your poor baby can be comfortable.
What worked best for my daughter was plain old oats crushed up and added to her bath water. It relieved the itch and inflammation quickly. Then once you find something to clear up the irritation, applying some kind of mild lotion every single day to keep the skin lubricated is a good preventative for further irritation.
Fortunately, my daughter’s eczema was temporary. She grew out of it by her second birthday. She occasionally gets some dryness, but I just get the oats out again and keep up with daily lotioning.
If you do try the oats (which couldn’t hurt and might help for your daughter too), try putting a handful in a stocking, tie the top and toss it in her bath water to “infuse” like a tea bag. Then squish it up. The goo that comes out of the oats is what relieves the redness and itch. Apply the gooey stocking to the red, irritated areas for a few minutes like a compress. Just don’t let her stay in the bath too long because that will irritate her skin more.
