fed 3 week old baby is very gy with every feeding and projectile vomits 1 to 2 times per day.?

All I have eaten today is oatmeal, Honey Bunches of Oats dry cereal, OJ, water, and apple sauce. I'm trying to eat only bland things and no dairy to make it easier for my baby. It doesn't seem to help though. What are baby's favorite foods? (Least likely to cause gas). I tried Mylicon drops which seemed to help, but she still vomited about 30 min. afterwards. Thanks!
