What to Wear

Among the long list of questions new parents have, one of the most common is...

..."what should my baby wear to sleep?" 

It can be stressful. You don't want them to be too cold or too warm, and it’s important that their sleepwear fits just right to keep them safe and comfortable as they snooze.

 At Tommee Tippee, we know all about safe sleep, so let us take you through the ins and outs.

One Sleepbag, all year round

Teaming up with sleep scientists, we’ve developed a dual-tog Sleepbag that can be worn in temperatures ranging from 14 to 27+°C.

Designed to be worn all year round, our new All Season Sleepbag has removable Zip ‘n’ Pop layers that mean you can adjust what your baby’s wearing as they sleep.

Made for little ones from birth up to 36 months, it’s super versatile and can change from 2.5 to 1.0 tog with ease, removing the need for loose bedding.

We developed this product with sleep scientists and a qualified paediatrician from Northumbria University, and it’s accredited by INPAA - a private Australian organisation that works closely with regulatory authorities, international affiliates, and industry members to improve infant safety.

What exactly is a tog?

Small babies find it difficult to regulate their own body temperature, so it’s important that you make sure their sleepwear is just right for the temperature of the room they’re sleeping in. To help you out, our sleep styles have tog ratings.

We know that tog sounds technical, but basically, it stands for Thermal Overall Grade.

It’s a measure of warmth, rather than thickness, and a value that’s determined by a lab test.

The higher the tog rating, the warmer the product.

While our tog ratings are really helpful, we always recommend that you check on your little one as they sleep to make sure that they’re not too hot or cold. You can do this by placing your hand on baby’s skin, don’t go by their hands or feet as they often feel cooler.

Select your size and style

Our sleepwear range grows with your little one, from birth to three years old...
