What do I need for a newborn baby?

Definitely either a stroller or a wrap or front pack. Diaper bag. Baby asprin and baby mylicon and orajel, thermometer, some sort of desitin or diaper rash cream (all good to have on hand kuds do get sick) i take it you will be bottle feeding, they sell these containers for formula that you can measure 3-4 bottles, its just good to have. If you're feeding., there is more stuff. Good luck and congrats
