Sleepee Snuggee & Tog Size Guide

Thanks for purchasing a Tommee Tippee Sleepee Snuggee. This product support page is here to help you use your new Grobag safely, and to ensure that both you and your little one sleep soundly.

Our Sleepee Snuggee is designed for use from 0 to 6 months.

What are the benefits of swaddling?

Swaddling is proven to improve quality young babies’ sleep. During the first months of their lives, young babies love to feel all snug and secure, just like when they were in mummy’s tummy. Having their arms tucked into their body mimics the closeness of the womb and suppresses their startle reflex (when their hands and body to jerk during sleep), so baby – and you – will get more sleep.

It also…

  • Keeps your little one warm during the first few months when their ability to regulate their own body temperature is still developing.
  • Helps them to focus on feeding by keeping their arms and legs tucked in.
  • Stops them scratching themselves with their nails as they sleep.

How do I wash my Grobag?

We recommend that you wash your Grobag before the first use. Always close the zip before washing, gentle machine wash at 40°C, and then reshape while damp or tumble dry on low heat.

You can use a warm iron but don’t iron over the back neck label.

SnugFit™ Intent

All our Grobags are shaped for a slimmer profile over the chest and waist, which enables full freedom of movement, without restriction or excess bulk. The bottoms of our Grobags are roomy, to allow your baby to adopt a natural, hip healthy “frog legged” sleeping position.

Zip fastening

The zip starts near the baby’s chin and finishes at their feet for improved comfort and reduced risk of skin irritation, as well as making it easier to comfortably secure arms inside.

When fastening, it’s important to make sure that the zip slider is fully engaged, right at the top of the zip before sliding to close.

The easy zip opening is also perfect for night-time nappy changes as you can unzip from the bottom, whilst keeping baby cosy and warm at the top.

Safety reassurance

Our Sleepee Snuggees conform to the European safety standard for children’s sleepbags EN 16781:2018 and the Australia/New Zealand nightwear standard AS/NZS 1249:2014.

SnugFit™ Intent

When should I transition my baby from a swaddle to an arms-out Sleepbag?

It’s time to move on from swaddling when your baby begins to show signs of rolling from their back onto their front. With our Sleepee Snuggee, you can release one arm at a time so that your baby can get used to their new way of sleeping. It may take a while for them to get used to, so try one arm out for a week or two, followed by the other arm.

Sleepee Snuggee Size Guide

Your child's head should not be able to pass through the neck hole when the Sleepee Snuggee is fastened. If it can, the Grobag is too big for them. Remember to check the weight of your child and refer to the chart below.

Sleepee Snuggee Tog Guide

What are togs?

A tog measurement is a European warmth rating: the higher the tog, the warmer the product. It’s a measure of warmth, rather than thickness.

Always consider the room temperature when selecting your child’s sleepwear, rather than the outdoor temperature. If you’re unsure, we recommend that you use a room thermometer.

The Sleepee Snuggee is available in three tog ratings…

0.2 Tog 1.0 Tog 2.5 Tog 3.5 Tog
For hot nights For warm nights For cool to warm nights For cold nights
24°C (75ºF) and above 20-24°C (68-75ºF)  16-20°C (61-68ºF)  16°C (61ºF) and below

Sleepee Snuggee What to Wear Guide

Several factors determine which tog rating should be used. These include the number of clothes your baby is wearing, the temperature of their bedroom and your baby's health.

Because all babies are different, we recommend that you check your baby regularly as they sleep by placing your hand on their skin to make sure that they’re not too hot or cold. Don't go by their hands or feet, as they'll often feel cooler.
