Loose blankets in the cot are a SIDS risk. Sleeping bags and swaddles solve that — baby stays warm without fabric near the face. Pick the right TOG for your room temperature and your baby will sleep through the seasons. All picks available on Amazon AU and Amazon US.

The picks — reviewed in detail
Halo SleepSack Wearable Blanket
The most-used sleep bag in both AU and US hospitals. Multiple TOG weights, hip-healthy design, inverted zip so you change a nappy without removing the whole bag. Indestructible build.
Love to Dream Swaddle Up
Arms-up swaddle — baby self-soothes via hands-to-mouth, but arms stay enclosed for the startle reflex. The transition Stage 2 model lets you wean one arm at a time.
ergoPouch Cocoon Swaddle Bag
Designed in Australia for the wider temperature swings of AU homes. Convertible swaddle (arms in or out via zip-off wings) and the TOG range covers everything from Darwin summer to Hobart winter.
Aden + Anais Classic Swaddle
Cotton muslin swaddles — same fabric as the muslin cloths. Soft, breathable, multi-use as a stroller cover or play mat. The traditional wrap-style swaddle for parents who like the technique.
Nested Bean Zen Sack
Lightly weighted chest panel mimics the feel of a parent’s hand. Polarising — some babies sleep dramatically better, some don’t notice. Worth trying if traditional sleep bags aren’t cutting it.
What we’d skip
- Loose blankets in the cot under 12 months. SIDS risk.
- Hooded sleep bags. Hood near face when baby rolls = re-breathing risk.
- Vintage hand-me-down sleep bags without TOG label. No way to dose temperature safely.
Frequently asked questions
When should I stop swaddling my baby?
Stop swaddling as soon as baby shows signs of rolling (usually 2–4 months). Continued swaddling once baby can roll is a SUDI risk. Transition to an arms-out sleep sack like the Halo SleepSack (arms-free) or Love to Dream Stage 2.
What TOG sleep sack do I need?
0.2 TOG for bedrooms 24–27°C, 1.0 TOG for 20–23°C, 2.5 TOG for 16–19°C, 3.5 TOG for under 16°C. Layer thinner clothing underneath in warm weather.
Are weighted sleep sacks safe?
Lightly weighted chest panels (like the Nested Bean Zen Sack) are considered safe for healthy term babies. Heavy weighted blankets and torso-wide weighting are NOT safe under 12 months.
