Currently 15 weeks pregnant with baby #2! This pregnancy seems like it is flying by but is making me more and more nervous by the day how do i handle 2 kids? My son will be 2 by the time this baby comes, i just keep thinking what am i going to do? I havent done this whole new baby thing for awhile now! How did you mommies handle 2 kids? And what necessities did you get for baby #2 that you didnt have for your first baby?
