The simplest carrier to get a newborn into solo — step-in-and-click, ideal for the fourth-trimester fussies.
For the newborn weeks, ease of use beats features, and nothing is easier than the Mini: you can put a floppy newborn in and buckle it entirely by yourself, front-in or front-out. It's snug, breathable in mesh, and perfect for contact-nap laps around the living room. The catch is it's outgrown around 9–12 months, so many families pair it with a longer-lasting carrier later.
