Before your baby is born choosing the items they might need is quite an overwhelming task. This tiny human is entering the world and their care is down to you. It’s understandable to be anxious.

When choosing baby sleeping products, there are only a few essentials that you need for their nursery:

  • A cot or moses basket
  • Mattress
  • Sleeping Bag
  • Room Thermometer

Why should you choose a baby sleeping bag?

The Lullaby Trust recommends the use of a baby sleeping bag as these can help prevent the risk of sudden infant death syndrome (SIDS). The advantages of using a baby sleeping bag is that they prevent your baby’s head from being covered by wriggling under bedding. Sleeping bags also ensure your baby stays at a constant temperature, reducing the risk of them overheating. When using a baby sleeping bag you don’t have to use any additional blankets or bedding. Baby sleeping bags also help babies to sleep on their back, which is the recommended sleep position by the Lullaby Trust and the NHS. Slumbersac baby sleeping bags all conform to the new British Standard (BS 8510:2009) so you can rest assured your baby will have a safe and comfortable night’s sleep.

What tog should I use?


Baby sleeping bags are available in a range of different togs (weights), for use in different seasons, and depending on the room temperature. The higher the tog rating, the warmer the sleeping bag, making it suitable for colder weather. Lower tog sleeping bags are suitable for cooler weather.

Please refer to our handy tog chart below, which also highlights what your baby should wear underneath their sleeping bag, depending on the room temperature. You should always check your baby to make sure they don’t overheat. Remember it is better to be cool than hot and it is quite normal for the baby’s hands and arms to be cool. Feel the nape of your baby’s neck – if it is damp then your baby might be too warm.

What size should I use?


Sleeping bags are also available in different sizes, depending on the age and height of your baby. The arm holes should be snug enough, so your baby cannot get their hands inside the bag. Slumbersac sleeping bags have underarm poppers on sizes up to 36 months to ensure a safe and secure fit. Your child's head should not be able to pass through the neck hole when the sleeping bag is zipped up, otherwise it is too big.


Sleeping Bags with Feet

Sleeping Bags with Feet are fantastic for active toddlers as they start learning to crawl and walk. The design offers them the freedom to move around, reducing the risk of them falling over, while still enjoying the comfort of their sleeping bag at bedtime. Some of Slumbersac’s sleeping bags with feet also feature feet covers with non-slip soles so children can walk around safely on slippery surfaces and keep their toes warm and toasty.
