Baby Sleeping Bags in Winter: Choosing the Right TOG Rating | Kindermaxx

Baby Sleeping Bags in Winter: TOG Ratings Explained Simply for a Safe Night's Sleep

As the temperatures drop outside, many parents ask themselves the same question: "Is my baby warm enough at night?" A baby who is too cold will sleep restlessly, but an overheated baby faces serious health risks. The solution to this dilemma is the TOG rating. But what does this number actually mean, and which sleeping bag does your child really need during the cold winter months?

In this article, we at Kindermaxx explain everything you need to know about TOG ratings, so you can sleep soundly—knowing your baby is safe and comfortably warm.


What Exactly is a TOG Rating?

TOG stands for Thermal Overall Grade. It is a universal unit of measurement that indicates how effectively a textile product (such as a baby sleeping bag or blanket) retains body heat. The higher the TOG rating, the warmer the sleeping bag.

Why is a Sleeping Bag Safer Than a Thick Blanket?

  • Safety: A sleeping bag cannot slide over your baby's face, which significantly reduces the risk of suffocation and overheating.
  • Constant Temperature: Your child cannot kick off a sleeping bag. This ensures their body temperature remains stable throughout the night.

Our Kindermaxx Experience: Choosing the Right TOG for Winter

At Kindermaxx, we often see parents rushing to buy the thickest sleeping bag as soon as the first frost arrives. However, our experience shows that the room temperature in the nursery is the deciding factor, not the temperature outside. The ideal sleeping temperature for a baby’s room is between 16°C and 18°C (61°F - 64°F).

For winter, we generally recommend these guidelines:

  • TOG 2.5: The standard winter sleeping bag. Ideal for rooms between 16°C and 20°C.
  • TOG 3.5: For very cold nights or bedrooms where the temperature drops below 16°C.

TOG Ratings and Clothing: The Equation for a Safe Night

The sleeping bag is only one part of the equation. The layers your baby wears underneath (bodysuits, pajamas) also count. A helpful rule of thumb is to consider the combined insulation of the clothing and the sleeping bag.

Room TemperatureRecommended TOGClothing Underneath
Above 22°C 0.5 TOG Short-sleeved bodysuit only
20°C - 22°C 1.0 TOG Bodysuit + light pajamas
16°C - 20°C 2.5 TOG Bodysuit + pajamas
Below 16°C 3.5 TOG Bodysuit + warm pajamas + socks

How to Check if Your Baby is Too Warm or Too Cold

Numbers are a great guide, but every child is unique. Trust your observations as the expert on your baby:

The Neck Check

Always feel your baby’s neck. It should feel pleasantly warm and dry. If the neck feels damp or sweaty, your child is dressed too warmly. Note that cold hands are not necessarily an indicator of freezing—as long as the neck is warm, your baby is usually fine.

Frequently Asked Questions About Winter Sleeping Bags

Is a sleeping bag with sleeves better for winter?

Sleeping bags with detachable sleeves are very popular at Kindermaxx. they offer great flexibility: if the temperature drops significantly in the early morning hours, the sleeves provide that necessary extra insulation.

Is a higher TOG rating always safer in winter?

No. Excessive temperatures are a risk factor for SIDS (Sudden Infant Death Syndrome). It is better to choose breathable materials and use layers (the onion principle) rather than putting your baby in an extremely thick, non-breathable bag.
