My wife has taken to bringing [Shepherd] into our bed at 4 a.m., which is a delightful experience. It’s kind of like sleeping next to a laundry bag with a live collie in it. There’s a heat pump thing with little kids, they throw off tremendous amounts of heat. So you also get the feeling of a small engine running on bad gas, knocking and sputtering all night. It doesn’t run smooth. So in between the vomiting and the defecation, it’s not only romantic to sleep with your wife, but you wake up feeling refreshed and ready to go.” -Jerry Seinfeld on the co-sleeping arrangement with his wife, Jessica, and son, Shepherd, 3.
