I'm due with our second this fall, and struggling to think of what we will need to buy to prepare for the new little one. We don't know yet if we're having a boy or a girl. But our first will have just turned or be about to turn 2, so we still have what seems like all the baby stuff. What did you find to be helpful and essential for your second? What was nice to have? What did you think you needed, but didn't end up using? Thanks all!
