These are nice covers and were my #1 in their newborn size options. They’re pretty roomy and wide through the bum. The Capri cover has flaps in the front and back to hold in an insert and help keep baby’s tummy and back dry. The Coverall version does not have flaps, but is a generally wider diaper cover. Blueberry also makes really wonderful AIO dipes called Simplex. You might get sucked in by their adorable prints.
