As for the itching, it could be numerous things. Allergies can be set off by touching things, too. For example, did you know that playdough and markers have gluten in them? I didn't until I found out my kids had to be 'gluten free'. It could be soy or many other things. It could be stress induced. It could be staph infection. Are you changing her sheets/pillow case often? For my son w/eczema I have to change it every 3-5 days, or the staph comes back.
For products, I would try Arbonne. It is pure, safe and beneficial. Arbonne has a line for babies/small children. It is also used by many adults, it's so good.
With Arbonne, the products are researched and tested over a panal of 100 people. If even one person comes back w/a reaction, they go back to the drawing board w/the formulation. It is formulated in Switzerland~where the standards of formulation are highest and manufactured in the US where manufacturing standards are highest.
If that doesn't work, talk to your pediatrician about Atopiclair. It's expensive, but it works. We use it in conjunction with a steriodal cream~only when it gets very bad~to keep it in check. Most of the warmer months, I just use Arbonne.
If you would like some Arbonne samples, information or some products feel free to email me ____@____.com or check out my ____@____.com
As said below, be sure and choose something natural and safe.
Good luck!
