S.,
Have you tried cutting out milk (temporarily at least)?
Also, my son was gas-sensitive to ANY amount of garlic/onion in prepared foods (like pasta sauce).
Once I got rid of all cruciferous (not hard, I wasn't craving and during pg I hated them for some reason?) this includes artichokes, broccoli and cauliflower, but others too, as well as onion, garlic, and milk, DS's tummy settled down as far as gas.
Oh and nuts are a factor too.
Some people don't want to get wigged out eliminating their diet, but these are the main ones - and I didn't know about artichokes - one dire night of gas for that one.
Good luck,
M.
