The topic of baby sleep can be a minefield for new and experienced parents alike, with everything from safety to routine causing worry and stress.

One of the biggest questions is what to put your baby to sleep in: we’re used to duvets and pillows as adults, but what on earth should a baby sleep in?

A sleeping bag is a fantastic idea for your baby, as they’ll keep him or her safe, comfortable and snug. A sleeping bag is, effectively, a wearable blanket that ensures your baby stays at a consistent temperature.

It should have lots of room for your baby to kick and move about. Unlike loose bedding, which is a safety hazard and can increase the risk of SIDS, a sleeping bag will be tailored for your baby’s size and weight, and will mean they can sleep soundly and warmly without the risk of overheating or getting tangled in loose sheets or blankets.

Getting your baby used to a sleeping bag early on is a great idea, as it creates a familiar sleeping environment for them, and they’ll soon start to associate their sleeping bag with bedtime. Your baby will find a sleeping bag just as cosy as a duvet, without any of the risks of loose blankets, pillows or sheets.

What size of sleeping bag is right for your child?

So what sleeping bag should you buy? You’ll likely need a few different ones as your child grows. The first thing you should think about is the size of your sleeping bag, which are usually helpfully grouped by size: normally either 0-6 months, 6-18 months or 18-36 months, but as you’ll see in our roundup, there are some brands that go beyond this age range too.

You should take care to make sure your baby meets the bag’s minimum weight, and that any extra poppers or zips are fastened carefully to suit the size of your baby, to make sure your baby’s head can’t accidentally slip down into the neck opening when done up.

What is a ‘tog’? Guide to the correct tog for your baby

Tog is another consideration. There are many options out there, varying from 0.5 tog to 3.5 tog, depending on the temperature in the baby’s room. A good year-round option is a 2.5 tog for temperatures between 16-20 degrees, while when it gets hot in the summer, you’ll want to put your baby in something lighter, such as a 1.0 tog.

Buying a room thermometer is a good idea, and there are lots of useful online picture guides to advise you about which clothes to put your baby in under the sleeping bag depending on the temperature.

What material should you chose for your baby sleep bag?

What else should you take into account? How the sleeping bag feels, of course: 100% cotton as a minimum standard will be soft and silky on your baby’s skin, while organic cotton, jersey or muslin may feel extra dreamy and cosy.

How a sleeping bag looks, of course, is of importance, too, as you’ll be using it nightly: you might like to match your sleeping bag to your baby’s nursery bedding, or to go for something neutral or brightly-coloured depending on your preference.

What additional features are worth looking out for?

There are also sleeping bags that offer more than just a lovely material or thick tog padding. You might like to invest a bit more for some premium features, such as cleverly-placed zips to make nighttime nappy changes easier, a travel pushchair belt opening to help you put your baby to sleep in their bag while on the move, or feet to give your baby added flexibility as they grow.

Made with super soft cotton in three adorable prints and two size options, the sleeping bag feels cosy and comfortable without being overwhelming or too warm in the sticky summer months.

In the winter, this can still be used, but with more layers underneath. If you love the look of the original illustrated designs, you can also buy coordinating bedding, which would look super cute in a nursery.

We also loved the generous size of the 6 to 18 month sleeping bag, which should allow for plenty of room even as your child grows beyond 18 months.

You’ll definitely need to buy multiple sleeping bags for your little one, so we love the fact that the Dreampod Sleeping Bag from British nursery brand Mamas and Papas comes with a handy pack of two in complementary designs.

We were impressed by the thick, cosy and soft feel of the 2.5 tog padding and 100% jersey cotton, while the spacious, generous size will doubtless last beyond 18 months. We also really liked the super sweet, gender neutral hot air balloon design, which is adorable without being garish.

The fact it comes in a pack of two saves time, effort and money, and means you’ll always have a spare when the other one is in the wash.
