The Ultimate Baby Wrap is basically a long piece of fabric you wrap around yourself in various ways to create comfortable spaces for your child to sit in against your body, and by the time Z was a year old it was basically the one carrier that worked well all the time. We liked the simplicity of it, as well as its portability and the variety of options such a simple design offered. The simplicity of the wrap style also allowed for minor adjustments that could make big differences in comfort for baby or parent. The verdict: Versatile, comfortable, and empowering, and great for both babies and toddlers. - Jennifer
