I STILL think that if you're a midwife and know that you'll be on call for a given week, or that one or more of your clients are at term, it's not unreasonable to keep a cooler well stocked with goodies so that you're ready to take responsibility for your own needs in this area. I hold to that. But I can also see where feeding yourself would present challenges if you're serving a rural area or working in a state in which midwifery is illegal and you have to operate underground.
IMO, this is ridiculous. A midwife isn't on call for one week JUST around YOUR due date. Most midwives begin their 24-hour availability for YOUR birth at 36-37 weeks and continue to 42-43 weeks. That's 6-8 weeks of 24-hours on call just for YOU. Midwives, as a general practice, have more than one client due in a month, and more than one client per year. Your average homebirth midwife is on call 24 hours per day, 365 days per year. Expecting a midwife to keep a cooler in her car "well stocked" 365 days a year is simply unreasonable.
