FAQs for Sleep Sacks

How Do I Choose the Right Size of Baby Sleep Sack? +-

Moreover, weigh your baby and measure their height, and then check the size chart to identify the most suitable one. Besides, the infant sleep sacks have to be snug fit but still not too tight.

Can My Baby Use Sleeping Bags Instead of Blankets? +-

For sure! As an alternative to traditional blankets, baby sleeping bags are convenient and safe, which reduces the risk of suffocation

How Often Should I Wash the Baby Sleeping Bag? +-

It is recommended to wash your baby's sleep sack regularly, as it may become dirty. Review the care instructions to prolong the life of the fabric.

Choose Your Perfect Warmth: The Nintara TOG & Size Guide

Because rooms and routines vary, your sleep sack should match your setup. For warmer rooms and AC, reach for our lighter baby sleeping bags; for cooler nights, the snugger option keeps baby comfortable without bulk. Use your baby’s height and weight to select the right size, neckline, and armholes should sit comfortably while legs have room to kick.

Remember: TOG = how warm your infant sleep sacks feel.

TOG at a glance

  • 0.5 TOG (lighter layer): For AC rooms, warmer cities, or sweaty sleepers. Airy, cool, and breathable, your everyday wearable blanket baby choice.

  • 1.5 TOG (cosier layer): For cooler evenings or rooms that run chilly. Comfortable and reliable sleep sack when temperatures dip.

Sizing (S–XL)

  • Measure first: Height + weight decide the size, not just age.

  • Fit check: Neckline sits flat, armholes comfy, belly/legs free to move.

  • Stage-by-stage: Transitioning from a baby swaddle sack? Start with S as a newborn sleep sack, then move to M/L/XL through infant and toddler stages.

Pro Tip: Most families love 0.5 TOG 0.5 for warm nights and 1.5 for AC rooms.

  3. Zip up for a snug, gentle fit on the torso, hips and legs stay free.

TOG-by-TOG Usage Cheatsheet

Our sleeping sacks for babies are available in a variety of sizes and styles, designed to accommodate babies of all ages and stages. Here’s a look at what we offer:

0.5 TOG

  • Best for: Humid cities, sweaty sleepers, daytime naps.

  • Wear with: Short-sleeve onesie or lightweight PJs.

  • Feels like: A breathable sleeping bag blanket alternative that settles fast without overheating.

1.5 TOG

  • Best for: Cooler nights, shoulder seasons, early mornings when temps dip.

  • Wear with: Lightweight long sleeves or footed PJs (depending on room temp).

  • Feels like: Comfortable and calm, your dependable sleep sack when you want a touch more warmth that still breathes.

Picking the Right Setup for Your Home

  • Match TOG to room temp: 0.5 for AC/warm rooms; 1.5 for cooler nights.

  • Prioritise fit over age: Size by height + weight for a safe neckline/armhole fit.

  • Plan rotation: Keep 2–4 infant sleep sacks (one in use, one drying, one spare). Add a compact nap sack bag to your diaper tote for on-the-go naps.

  • Transition smoothly: Moving from baby swaddle sack? Use a snug newborn sleep sack first, then size up as mobility and height increase.

Bonus: Mix TOGs across your rotation, 0.5 for day naps, 1.5 for early-morning chills.

Care That Keeps Your Baby Sleeping Bags Soft

  • Wash: Machine wash cold, gentle cycle, mild detergent.

  • Dry: Tumble dry low or line dry in shade.

  • Zip first: Fasten zippers before washing to help preserve shape.

  • Skip harsh bleach: Protects colour and fabric handfeel.

  • Store smart: Fold and stack within easy reach so a clean sleep sack is always ready.

Laundry Hack: Wash sleep sack baby items with other soft baby linens to minimise abrasion and keep the handfeel plush. Our baby products are designed to offer the best care for your baby.

Real-Life Fit: How Many Do Families Use?

Most homes feel covered with 2–4 infant sleep sacks: one in the cot, one drying, one spare in the bag. If you travel or split time between rooms, the 0.5 TOG Set of 3 keeps rotation effortless and cost-efficient, your everyday wearable blanket lineup with zero late-night laundry stress.

Bonus: Keep a labelled zip-pouch with a spare sleep sack baby, wipes, and a fresh onesie, your “bedtime go-bag” for grandparents’ place or quick weekend trips.

Quick Buying Checklist (Save & Screenshot)

Warmth: 0.5 TOG for AC/warmer rooms; 1.5 TOG for cooler nights.
