You know how to do the car seat tango: Pop it in, drive around, pop it out, lug, lug, lug. To help you with those last painful steps, there’s Itzy Ritzy’s Wrap & Roll. The smart invention is a pad that wraps around an infant carrier handle to cushion your arm while you’re lifting the car seat. And it has another trick up its sleeve: It unrolls to become a play mat. Made from soft cotton and minky, the machine-washable circle can be spread out for tummy time (it comes with a mirror and toy loops to keep littles occupied). In a pinch, you can also use it as a changing pad or blanket. You have to love a product that does so many things — all without taking up a lick of space in your diaper bag. And that’s no song and dance.
