D.,
First of all, good luck and congratulations! I have 4 children, breast fed them all, and dealt with severe colic starting with my first. Breastfeeding was painful and overwhelming-it did not feel natural at all. By the time my first born was two weeks old, I weighed less than my prepregnancy weight, becuase of all the things I could NOT eat. It was frustrating hearing all the items not to eat without hearing what to eat. I'm sure you are finding the same. Post a list of the "yes" items and it won't feel so overhwelming.
Following is a list of some foods to include and some to avoid. The avoid list may seem dramatic-just try your way through it-not every one has to avoid all of them-find what works for you.
Foods to avoid:
brocolli
cauliflower
brussels sprouts
garlic
onions
cabbage
cole slaw
orange juice
grapefruit or grapefruit juice
prunes
plums
raisins
tomato sauce
chocolate
caffeine
beans-(legumes type, not green)
spicy foods-mexican, Indian, etc.
dairy (try soy products-though my children were also allergic to soy!)
some folks even need to avoid (I did):
peas
strawberries
other citrus fruits
cantalope
apples
wheat products
peanut butter, nuts
Foods which should be safe:
chicken
fish
rice
pasta
squash
carrots
pears
applesauce
grapes
bananas
green beans
tofu
cottage cheese
yogurt (may need soy)
Give it your best shot but if it it too difficult, it really is okay to bottle feed. Good luck!
