I went with 5 wondersuits, 5 singlets, 1 nightie, 1 hat, 1 going home oufit and 5 blankets of varying thickness. I was only in for 40 hours, so it was waaaay too much, but for a longer stay it's about right. If you do have a super pooper, or a spewy louie (like mine) you can always send stuff home to be washed.
