A swaddle can feel like a warm, familiar hug for a newborn. In my 18+ years as a Newborn Care Specialist, I’ve swaddled hundreds of babies, and I always tell parents the same thing: how you swaddle matters just as much as the swaddle you choose.

My simple swaddling rules

• Always on the back. A swaddled baby goes down on their back, for every nap and every night.
• Snug at the chest, loose at the hips. You should be able to slide two or three fingers between your baby’s chest and the swaddle. The legs should be able to bend up and out freely, never wrapped straight and tight.
• Thin and cozy, not hot. Use a light swaddle and dress your baby simply underneath. Sweating, damp hair, flushed cheeks or fast breathing can mean your baby is too warm.
• A bare crib. A firm, flat mattress with a fitted sheet, and nothing else: no loose blankets, pillows or toys. A swaddle that has come undone counts as a loose blanket, so take it out.
• Their own space. Your baby sleeps in their own crib or bassinet, close to you, but not in your bed.

When to stop swaddling

Stop swaddling as soon as your baby shows signs of trying to roll over. For some babies, that can be as early as 2 months, but every baby develops differently, so keep watching your baby’s cues. This is when an arms-out stage helps: one arm out first, then both, so your little one gets used to sleeping with free arms. Talk with your pediatrician if you’re not sure your baby is ready.

A little help from MiMiSwaddy™

I designed MiMiSwaddy™ with these moments in mind: a zipper for easy diaper changes, room for little legs, and arms in or out, so the same swaddle can carry you into the transition stage.
