Nobody warns you that parenting is partly a forearm workout. Twenty minutes of patting, then thirty, then the baby stirs and you start over. My arm gave out long before my determination did. A friend showed me Sleepy Baby, and I was doubtful until I tried it. It’s a soft plush paddle that pats at a steady rhythm while a built-in white noise track plays. You choose the speed, strap it on with the belt, and let it do the repetitive work. Charging takes about 1.5 hours, and a full battery lasts up to 7 hours of continuous use. It’s CPC certified and made with baby-safe materials. I’d spent weeks reading about infant sleeping devices, and most felt bulky or complicated. This one is simple enough that I could set it up half-asleep, which is exactly when I needed it. The 30-day money-back promise helped me say yes. If you’ve ever switched arms mid-pat, you know why this matters.
