Your baby keeps waking themselves up. You re-swaddle. They escape again. You re-swaddle again. It's 3am and this has happened four times. The swaddle isn't failing because of your technique - it's failing because it was never built to the right proportions for a newborn. A 0-6m label means the fabric is sized for the biggest baby in that range. On a 3kg newborn there's slack everywhere, and that slack is how arms get out. Precision-sized for actual newborns, not a range that spans six months, so the fit is snug from day one and not loose until month four when they've grown into it. Zip closure means no technique required at 3am - velcro takes skill to execute half-asleep, a zip takes one motion and gives the same result every time. Arms stay down through the Moro reflex because when the startle fires the bag absorbs it and arms can't escape to the face to trigger a full wake cycle. Holds through 100+ washes because the zip doesn't lose grip the way velcro does, so month three feels the same as night one. Works anywhere - cot, bassinet, travel crib, pram, grandma's spare room - the settle is the same wherever you are because the swaddle is the same. Pure cotton keeps it breathable all night so no overheating, no sweaty unsettled baby waking from temperature rather than hunger. The Moro reflex fades around 4-6 months. Until then, every night without an escape is a night everyone sleeps.
