How to use the Sleep Suit Sack

Learn how to use the Sleep Suit Sack in either Sleep Sack or Suit mode, for safer, comfortable sleeping

The Sleep Suit Sack is a Sleep Sack and Sleep Suit in one! With the use of some clever zips, you can transform between a Sleep Sack and a Sleep Suit with legs. Here we explain the features of our most popular and loved sleep sack product for your child, and offer some tips and tricks on how to best use the product to get more sleep.

Step one

Sleep Sack mode
Use like a regular Sleep Slack.

Suit mode
Unzip the leg portion of the Sleep Suit Sack. Fasten the front zip to the back zip and repeat on the other leg.

Step two

We suggest only opening the upper zips to dress your child. In an upright position, put your child's legs through the legs of the Sleep Sack and then their arms through the sleeves. If it’s easier, you can dress your child in a lying down position.

Step three

To change a diaper or to use the toilet, unzip from the legs, three quarters of the way down.

Step four

To use in a 5 point harness, ensure the Sleep Sack is in Suit mode with legs.

Safety warning
Do not use a padded Sleep Suit Sack (2.5 or 3.5 TOG) in a car seat.

Step five

Refer to the Room Thermometer and Dressing Guide included with every new pouch for guidance on how to choose the right TOGs and layers for your child.

Step six

Always sleep your child in a safe sleep environment. A loose blanket is not required when using this product.

SHOP THE SLEEP SUIT SACK

Let’s check the fit!

An important safety element when using the Sleep Suit Sack is to ensure it's correctly fitted to prevent the product from riding up around your child’s face during sleep. Here’s how you can check you’ve got the right size. The Sleep Suit Sack is suitable from 3 months of age, please do not use a Sleep Suit Sack on a newborn.

Check you have the correct size according to your baby's weight using our Size Guide.
Put the Sleep Suit Sack on your child as you intend to use it (Sleep Sack or Suit mode).
Slip two fingers into the neckhole of the Sleep Suit Sack and onto your child’s chest. The material should feel firm and comfortable on your fingers, but not tight.
Check your child’s hips and legs. Your child’s knees should be able to flop outwards in a frog like position without any restriction.

Please do not be tempted to upsize, to get more wear out of the Sleep Suit Sack. A larger size may cause the material to gather around your child's face.

If in doubt, feel free to chat to our friendly Customer Service team who can help you check the fit for your child.

Understanding TOG ratings

Your Sleep Suit Sack comes with a TOG rating. TOG stands for Thermal Overall Grade and is a unit of measurement for insulation and warmth of sleepwear and bedding. Put simply, the lower the TOG rating the lighter the fabric. The higher the rating, the more padded and insulated it is for warmth. TOG rated fabrics are important as your baby cannot regulate their temperature like adults can.

Included in your pouch packaging is a Room Thermometer and Dressing Guide. Simply read the thermometer to find the room temperature of your baby's sleep environment, then follow the Dressing Guide on the front of the thermometer. The guide will inform how to layer your baby for sleep based on the TOG rating of your pouch, and the temperature of your room. Simple, smart and sanity-saving!

Understanding TOG ratings

What TOGs does the Sleep Suit Sack come in?

Choose from five TOGs for comfortable sleeping no matter the temperature.

FAQs for using the Sleep Suit Sack

What size Sleep Suit Sack should I buy?

3–12 months: We recommend Sleep Sack mode
8–24 months: We recommend Suit mode around 12—15 months of age, when your little one starts to walk.
2–4 years: We recommend only using Suit mode to prevent injury in the event of crib climbing or leaving the bed during the night.

6–8 years: We recommend only using Suit mode to prevent injury in the event of crib climbing or leaving the bed during the night.

Do I use blankets on top of the Sleep Suit Sack?

The Sleep Suit Sack is TOG rated meaning they have an insulation grade making them warm enough to use for sleep without loose bedding, and are designed to replace blankets. It is recommended by safe sleep guidelines to sleep your child with their face and head uncovered, in their crib free from loose bedding, pillows and toys.

How do I know if I have the right TOG to keep them warm enough?

Included in your Sleep Suit Sack packaging is a thermometer and dressing guide. Place the thermometer in your child's sleep environment to check room temperature. Once room temperature is established, use the table to guide you on the correct TOG and under-Layers combination. The Sleep Suit Sack comes in four different TOGs to ensure your child is comfortable no matter the room temperature. Our organic cotton fibers are excellent at keeping your child warm, while being breathable to maintain a comfortable and safe sleeping temperature.

Why are the sleeves on the 2.5 and 3.5 TOG not padded?

As a baby regulates their body temperature through their arms and head, ergoPouch 2.5 TOG and 3.5 TOG Sleep Sacks are padding free in the sleeves.

How do I stop my child from removing their Sleep Suit Sack?

Those independent fierce toddlers do not just discover their legs and walking once they reach toddler-hood. Their fine motor skill development often results in the discovery of zips and buttons on their Sleep Sack. It is not uncommon for a toddler to remove their Sleep Sack once you put them down for sleep. Parents have reported success with differing techniques, give one of these a go!.

1. Use the product in Suit mode
If you have the product still in Sleep Sack mode, it may be that your wriggly toddler just needs their leg freedom to be comfy during sleep. Go ahead and try out the Suit mode to see if it makes a difference.

2. Change the TOG
In some cases, your toddler may feel too hot and be removing it for comfort. If this is the case, check the room temperature and what TOG you are using. Use a lighter TOG if needed.

3. Ensure the zip cover is done up
The zip cover is a little fabric flap with a press-stud dome, that goes over the zip guard to prevent curious fingers from accessing and undoing the zip. Ensure this is done up when you put them down for their sleep.

4. Wear backwards or inside out
If your wily toddler has figured out the zip cover and nothing can stop them unzipping and remove their Sleep Suit Sack, try putting the product on them backwards, or inside out.

5. Try a different color or print
We often get told by parents that their child prefers a particular color or print in our range. Our Sleep Suit Sacks come in various prints and colors. Wearing their favorite color may help your head-strong toddler or preschooler settle in for sleep more easily.

Can my child walk around in the Sleep Suit Sack?

There are grip pads on the bottom of the Sleep Suit Sack to assist in walking safely if necessary for overnight bathroom trips, or sleepwalking. For safety, we do not recommend the Sleep Suit Sack is used outside of sleep as apparel. As the Sleep Suit Sack acts as a sleep cue, we strongly suggest dressing your child in it just before bedtime/lights out to give them the signal that it’s time for bed.

What does my baby wear under the Sleep Suit Sack?

This will vary from a diaper; to underwear if your child is toilet trained; through to warm pajamas/onesies depending on the room temperature. Follow our What to Wear dressing guide (included with your Sleep Suit Sack) to layer appropriately underneath, according to your room temperature and what TOG you use. ergoPouch's Rompers and Pajamas are also TOG rated to help make dressing for sleep easy.
