Hi J.!
Here is an article about what it normal for spitting up and what is not, written by an MD. Basically, if your baby is still gaining weight and healthy (in other ways), there's nothing to be worried about, but there are some things you can do to make them more comfortable until they grow out of it.

On the other hand, what you're describing might also indicate some allergies. What YOU are eating, the baby is also eating, so you might want to cut some things out of your diet to see if that helps (note: it takes a week usually for the baby's system to clear, so cut for a whole week). Ask around in your family and your husband's family for any odd allergies that might have affected family members when they were babies. But if there's nothing, try cutting milk and/or soy - the major allergies for babies. Read your labels carefully - those two seem to be in EVERYTHING.
Good luck!
