Baby Sleeping Bag Tog Guide

It’s important that you think about both comfort and sleep safety when putting your baby to bed. There are many different varieties of sleeping bag tog for a range of different seasons, read on to find out which sleeping bags are right for your baby. 

The Benefits of a Baby Sleeping Bag

Baby sleeping bags are another alternative to blankets, which will keep them comfortable and at a safe temperature whilst they sleep. Sleeping bags are much safer for babies than blankets at night time as they stay in one place, therefore reducing any risks of sudden infant death syndrome through suffocation. 

Here are some of the other benefits of baby sleeping bags:

  • Putting your baby in a sleeping bag will help to regulate a constant temperature. 
  • There is no need for any additional blankets or covers in your baby’s cot that they could get tangled up in. 
  • Baby Sleeping Bags promote good sleep and become an important part of your baby’s bedtime routine early on. 
  • Your little one can move around freely and still be covered and cosy. There should also be no need to constantly check your baby through the night.

What Size Sleeping Bag Should my Baby Wear?

Your baby’s sleeping bag should not be too big or too small, remembering to check the weight and height of your child against their sleepwear size is really important. 

These are our recommendations for a comfortable and safe sleeping bag, but every baby is different, use this as a guide.

What Tog Sleeping Bag Should my Baby Wear?

Choosing the right tog (Thermal Overall Grade) of your baby’s sleeping bag is a measure of the warmth, rather than the thickness - the higher the tog rating the warmer your baby will be. 

Here is a breakdown to help you decide which tog your baby should be wearing, and when. 

3.5 tog - baby sleeping bags with a 3.5 tog are usually designed for winter months when the room your baby is sleeping in gets to 14 degrees or below. 

2.5 tog - if you have a 2.5 tog sleeping bag this is great for all-year-round use with room temperatures between 14-20 degrees.

1.0 tog - designed for much warmer weather, a 1.0 tog is suitable for temperatures between 20-24 degrees when it’s too hot to put your baby in anything heavy.

0.2 tog - sleeping bags with a 0.2 tog are designed for heatwave-like temperatures, which is great if you’re going on a family holiday somewhere warm. Ideal for temperatures 24 degrees and above. 

What Should Babies Wear with their Sleeping Bag?

All babies are different, however, the general recommendations are the warmer the room, the fewer clothes your baby is going to need. If the weather is 14 degrees or under we would recommend putting your little one in a long-sleeved cotton bodysuit as well as a sleepsuit for the colder nights. However, on the other hand, if the weather is 27 degrees or more then you’re just going to want to put your baby in a nappy with a 0.2 tog sleeping bag.
