I've never been more passionate about a pair of pajamas. The Jane Maternity & Nursing Thermal Pajamas ($33) are the softest, coziest PJs I've ever owned. The leggings have a high waist, which is so comfortable on your postpartum belly (and/or C-section scar), and the long-sleeved top has a slit for easy breastfeeding. The fabric is somehow superthin but warm for cool nights (or colder body temperatures, a weird postpartum side effect that hit me), and even if these are warmer than you want to sleep in (especially at first, when you might be having those annoying night sweats), then they're great to wear lounging around the house in those early days, when you don't want to get dressed and wear real clothes but still want to look semi-human. I got them as a gift, and plan on to pay it forward by giving them to every pregnant friend I have.
