If you’re tossing and turning at night, the rest you’re getting is not restorative. Many moms rely on special body pillows, like the Leachco Snoggle Total Body Pillow, designed to support your back and be tucked between your knees. But really, you don’t have to shell out cash to get the zzz’s you need: Gastelu says simply placing any old pillow or cushion between your knees will help ease any lower back and hip discomfort that you may experience while sleeping on your side. “Keeping the knees level reduces the strain on your joints,” she says. You can also prop a pillow behind your back for additional support and comfort while side-sleeping, which is recommended during pregnancy.
