P.S.
When my baby was just 2 days old she couldn't hold anything down, the doctor gave her mylicon but it didn't help. Many people advised grape water which helped but only for a while, my baby developed reflux. After changing to several milk based formulas I realized she was allergic to cow's milk, so I asked my pediatrician. He said she would be fine drinking a soy based baby formula, and that babies eventually outgrow that allergy in most cases. I recommend you ask you pediatrician about it. When my daughter was about 2 years old I started giving her very small quantities of cow's milk, now she is no longer allergic to it.
