Many of my Labor Foods recommendations are quick just-add-hot-water meals. When you're laboring at home or a birth center, your access to boiling water is easy. If you are heading to a hospital, they have plenty of water and occasionally a microwave, but you can save yourself the hassle and just pick up a small electric kettle. I don't generally like the collapsible silicone ones because they are going to have boiling water in them and sometimes they collapse when you don't want them to.
I recommend this one because it is big enough to do something for the laboring person and something for the support person at the same time, but no bigger.
