Baby #2 must haves

My friend wants to throw me a shower for baby number 2. Which will be my second girl. But I kept everything (bassinet, car seat, stroller, swing, etc...) from baby #1

What I NEED is a big girl bed for first daughter. And maybe a stroller for two?

Daughter will be 3.5 when baby comes. What are your baby #2 MUST HAVES ?
