Temperature Information

What is a TOG rating?

Finding the right TOG rating and dressing your baby appropriately for the temperature can be confusing. Every baby feels hot and cold differently, ambient temperatures fluctuate, and layering impacts thermal effectiveness. It's not a one-size-fits-all approach, but understanding these factors can help.

At Love to Dream we use the industry-recognised measurement system, called TOG. TOG stands for Thermal Overall Grade and helps simplify the process of choosing the right garment/s for your baby. Put simply: The lower the TOG rating, the lighter the fabric. The higher the TOG rating, the warmer the fabric.

  • Products with a 0.2 TOG Rating are ideal for Room Temperatures between 24-27°C.
  • Products with a 1.0 TOG Rating are ideal for Room Temperatures between 20-24°C.
  • Products with a 1.5 TOG Rating are ideal for Room Temperatures between 18-22°C.
  • Products with a 2.5 TOG Rating are ideal for Room Temperatures between 16-20°C.
  • Products with a 3.5 TOG Rating are ideal for Room Temperatures below 16°C.

The clothing guide link below provides with guidelines around how to dress your baby/toddler based on the room temperature. It is only a guide. All babies are different. The number of clothing layers may vary according to a baby’s health, their physiology, and the room temperature in the room. The caregiver must determine what is suitable. We recommend that carers always monitor the temperature of the room & the child’s comfort. It is important to check your baby regularly to ensure that they are comfortable and that they do not overheat.

Sleep Bag FAQs

When should my child use a sleep bag?

Once your baby has started rolling and fully transitioned out of swaddling, a sleep bag is the perfect next step.

Our sleep bags provide plenty of room for growth and are available in various TOG ratings for all seasons. They offer a sense of familiar comfort that helps maintain a consistent sleep routine as your child grows.

What tog sleeping bag for toddler in winter?

The right TOG rating depends on the temperature of your toddler's bedroom.

For winter, you’ll likely need a 2.5 tog for room temperatures between 16°C and 20°C or a 3.5 tog TOG rating is ideal for room temperatures below 16°C.

Combine with a breathable base layer to ensure they stay warm without overheating.

Are sleep bags suitable for restless children?

Absolutely! Sleep bags are ideal for restless sleepers because they act like a secure blanket that stays in place no matter how much they move.

This removes the safety concern of loose blankets being kicked off or tangled, ensuring your child stays warm and safe throughout the night.

Is my toddler ready for blankets?

Stop the midnight blanket check. A Love to Dream™ sleep bag provides the warmth of a blanket without the safety risks of loose layers.

It serves as a powerful sleep cue that signals it's time to rest, while the secure fit ensures your child stays cosy throughout the night—even if they’re a restless sleeper.

It’s the simplest way to ensure a safer, longer sleep for the whole family.
