Been there-done that! I had a child that also had reflux. I totally understand what you are going through. Like your baby, mine also took zantac along with reglin. It didn't help either. They are right, your baby will outgrow it. Projectile vomiting is no fun to live with. There are a few things that you can try to maybe help. Most did not help with one of my children but they did with another,maybe they will for your baby. Try sitting the baby in a carseat carrier right after eating. My first child responded to this. Leave the baby in it for 30 minutes to an hour. Do you ever give the breast milk from a bottle? If you do, try adding about a half teaspoon of rice cereal to the bottle. My ped. recommended this and it helped my first. Burp the baby twice as much as you have been doing. Maybe one of these will help or you may have a baby like my second child- nothing helped - nothing. She finally stopped the projectile vomiting at about 1 year. And even after that she would occasionally vomit. She finally quit at about 1 and half. Best of luck to your family. Its hard for a lot of other parents to understand what you are going through. God bless!
