Chiming in a little late here, but wanted to comment that when I was pregnant my doctor told me that sudafed was ok for me to take if my allergies got to the point where I couldn't function (or benadryl, if it was runny/sneezey time) - she told me that it was only becuase my BP was always, always, always the same safe level (110/70), becuase it does tend to raise BP. I used to take ibuprofen for my back and was told that that is NOT safe to take during pregnancy... so on days when my back was really acting up I would take 2-3 tylenols, which barely made a dent in the pain but better than nothing. My best friend had a baby in September and her doctor forbade her from taking any meds for her allergies - benadryl was the only safe thing in her book... bottom line, for the more 'common' cold/flu drugs it really seems to vary from OB to OB what is safe and what isn't safe to take. I like
http://www.marchofdimes.com/ for
non-scary reliable pregnancy/breastfeeding advice. Non-scary is KEY when you are pregnant and doing internet research - there are SO many different interest groups who mask their intentions with a somewhat neutral looking site - but when you dig deeper you find that they are really an anti-specific drug company- group, or anti-baby formula group, etc...
As far as formula goes, nowadays formula is fda regulated and has JUST as many nutrients as breastmilk. My best friend is a la leche league leader, and has had 3 women turn to formula becuase nursing just wasn't working for them (and pumping was way way too much work)... She couldn't nurse her own son due to meds that she needed to get back on as soon as she delivered him. Believe it or not, "store" or "cheaper" brands of formula are just as safe and healthy as the more expensive brands. The main benefit of nursing, aside from the monetary one

, is the reduction of ear infections, colic/gas, and overall resistence to colds that babies get directly from their mothers - this is due to the actual act of latching on and drinking directly "from the tap" - and not becuase of the breastmilk itself... I agree though, that nursing is the way to go. It's so easy in the beginning when everyone is sleep deprived, to just roll over to get the baby, latch it on, and doze while it eats! And there really is nothing like the bonding that happens during that time.
*off my soap box* lol!
