Like all swaddles, the Zen is made for babies up to 4 to 5 months old (and up to 14 pounds), who are still battling that annoying Moro or startling reflex, which can cause them to awake easily in response to the feeling of falling. But unlike a simple blanket, the Zen has those soothing, weighted, chemical-free poly-beads and is designed for easy use in four quick steps. The swaddle is also designed to grow with your baby. An interior leg pouch gives a smaller babe a snug fit, but you can forgo the interior pouch for more legroom as your baby gets bigger. This swaddle doesn't come cheap at $40, but what do you think? Is it worth the investment for the new technology? Or will you stick to your old blanket? Weigh in below.
