Jackie's hack keeps her baby's feet inside the pajama footies.
My second child, while weighing a perfectly acceptable 7 lbs 12 oz, is a dainty little thing and her feet were getting lost in the legs of her one-piece sleepers. I discovered if you put socks on over the feet of the sleepers it keeps them in place. No irritated baby because she's got both feet in one leg of her pajamas! Plus it keeps her feet warm.
