Has your baby been given anything for the reflux?  My two last babies had this and if they had been CAH and salt wasters, I don't know how I would have coped.  It is bad enough that most babies spit up anyhow occasionally, never mind having reflux.  I know that my doctor prescribed Infant Gaviscon for reflux and then we switched to a formula designed specially for babies with reflux when they came off the breast.  This might just help, on top of the usual advice given above.  I was always advised to err on the side of caution and re administer if my son vomited within thirty minutes of having his medicine.  It might help to delay the feed until thirty minutes after meds for a little while to ensure baby does keep his/her medicine down.  Especially if he /she has reflux....... Mine grew out of it shortly after 6 months of age.
