Both ladies who answered before me gave wonderful advice. I had planned on touching basis with both suggestions. For starters, to lower the chances of your infant spitting up, feed her at an incline, and give her small increments of food at a time. (i.e. mealtimes let her drink 2 ounces, then burp her, 2 more ounces, then burp, etc until bottle is emptied.) This helps lower the chances of the amount of spit up. If consuming the bottle real fast, or all at once she's more likely to extract it as soon as she's done. Even have her sleep in an incline (they sell the cheese shaped wedges with the slight incline for infants in many places).
Also, if the spit up is more like a projectile vomit and in the amount you suggested, she may in fact have a reflux problem. It's called GERD (Gastro Esophageal Reflux Disorder).
Three of my children had it as infants. Two grew out of it, my daughter (now 11yrs) is on meds still. It's hereditary in our family.
In agreement with the other responders, Talk to your pediatritian concerning this issue. They may schedule an upper GI (which is an easy procedure where they have your child drink a cocktail that glows in their stomachs so they can see through x-ray where the cocktail travels.)
My daughter's a lifer on her meds. Many kids grow out of it, she's just the lucky duck who gets to stay on meds for life. Currently they have her on prilosec. If she isn't consistant at taking her meds she will up-chuck her food.
Typically kids with GERD know what their stomach's can and can't tolerate, so people think it's funny when my daugher will pass up chocolate, or rather hit the salad bar instead of devouring pizza. She has to drink carbonated drinks sparingly, and still has to sleep in an incline.
Good luck!
