She's much better now, thank God. Although I still worry for when she starts solids in 3 months time, I'm hoping she will outgrow the allergy soon.
Iberogast is a herbal preparation, you can get it over the counter from the pharmacy but you could ask your doctor about it first. I know of a friend (she's a pharmacist) who used it on her baby for reflux and was quite happy with it. You can get more information on the product on their website: http://www.flordis.com.au/product/iberogast
