Baby Medicine Question?

I'm a FTM due in about 5 weeks and am now just getting the last little things I need for my baby girl! One of these things I wanted to get squared away was a baby medicine stockpile, but there are so many different medicines out there that I truly have no idea what to get. So my question is, what medicine do you moms (or dads) think is necessary to have on hand from day one? I not planning on doping my kid up at all, I just don't want to realize I need something at 3am some time and not have it handy. Thanks!!
