Sleep Sacks and Swaddles

Sleep sacks and swaddles are the foundation of a safer sleep setup, designed for parents who want to replace loose blankets with wearable layers that stay put through the night and across every nap. TOG rating is the key variable: a 0.5 TOG suits warm nurseries above 74°F, a 1.0 TOG covers most year-round rooms between 69 and 74°F, a 2.5 TOG handles cooler spaces between 61 and 68°F, and a 3.5 TOG is built for drafty or cold rooms below 61°F. Fabrics across the collection run from OEKO-TEX certified organic cotton to bamboo and merino, with two-way zip designs that make middle-of-the-night diaper changes far less disruptive. Bambi Baby carries sleep sacks and swaddles sized from newborn through toddler, including transitional swaddles with removable wings that move with your baby from arms-in comfort to arms-free rolling, so one product carries you through the most critical early months rather than requiring a second purchase. Pair your sleep sack with a firm, breathable option from our crib mattress collection to complete an AAP-aligned sleep space built around your baby's actual room temperature.

What's the difference between a swaddle and a sleep sack?

A swaddle wraps the arms in to mimic the womb and calms the startle reflex in newborns. A sleep sack leaves arms free and is used once your baby can roll, typically from around 8 weeks onward.

When should I stop swaddling my baby?

Stop swaddling at the first signs of rolling, usually between 8 and 12 weeks. Move to an arms-out wearable blanket so your baby can reposition safely.

What TOG sleep sack do I need year-round?

A 1.0 TOG covers most nurseries between 69 and 74°F. Keep a 0.5 TOG for summer and a 2.5 TOG for winter, and adjust the layer underneath rather than buying multiples of every weight.
