🌿 Wash with Love:
Our Sunday Sleep Bag is designed to be washed on a gentle cycle with cold water and only other bamboo fabrics. Please note that Bamboo is a natural fiber and is delicate; so it should be washed separately from items that may be damaging — like towels or velcro. Sleep Bags should NOT be washed inside out, but should be zipped up completely to protect the inner quilting.
☁️ Dry Naturally:
We do not recommend using the dryer to dry your Sunday Sleep Bag. Instead, hang or lay flat to dry. Make sure to open your Sleep Bag when drying — just like a blanket or quilt, they can take longer to dry. If you do choose to use a dryer, please tumble dry on low.

⭐️⭐️⭐️⭐️⭐️ "So impressed with how soft and well thought out the design of this sleep sack is! As a first time mom I have been so lost in the sleep sack world and didn't know what to get for my wiggly baby, especially after transitioning her out of her swaddle. A friend of mine suggested using a wider base sleep sack for more comfort and this sleep sack offers just that!" - Eila G.

Frequently Asked Questions
Why should I choose bamboo?
Bamboo fibres create an incredibly soft fabric that is both gentle and cozy to the touch. The fabric is hypo-allergenic and soft on both sensitive skin and eczema. Sunday Littles fabric is made from 95% viscose from bamboo and 5% spandex which allows for great breathability and stretch for long-term wear.
What does OEKO-Tex® Standard 100 Certified mean?
100% of our curated pieces at Sunday Littles carry the STANDARD 100 by OEKO-TEX® label. This means that every single element of each piece—down to the smallest detail—has been independently tested for over 1,000 harmful chemicals, meets OEKO-TEX's strict criteria, and is certified 100% safe. And we mean Every. Single. Element.
What is a TOG Rating?
The TOG Rating is a measurement that indicates the thermal insulation of bedding and sleepwear, helping to determine how warm or cool a fabric will keep a person.
- 0.5 TOG: Very light, suitable for hot weather.
- 1.0 TOG: Light to medium warmth, perfect for autumn and spring
- 2.5 TOG: Provides increasing warmth for cooler temperatures, suitable for winter.
Understanding TOG Ratings is essential for selecting appropriate sleepwear, like our Sunday Sleep Bags, ensuring comfort and safety for your child during sleep.
What are the benefits of using a sleep bag instead of a traditional blanket for young children?
Choosing a sleep bag over a traditional blanket can offer several advantages, especially for infants and young children:
- Safety: Sleep bags reduce the risk of suffocation and entrapment, as they keep the baby’s head covered and prevent them from becoming tangled in loose bedding.
- Temperature Control: Our Sunday Sleep Bags come in different tog ratings (0.5, 1.0 and 2.5), allowing parents to select one that matches the room temperature, ensuring the baby stays warm without overheating.
- Mobility: Our Sunday Sleep Bags allows babies to move their arms and legs freely while keeping them warm, unlike blankets that can easily be kicked off.
- Consistency: Sunday Sleep Bags provide a consistent sleep environment, as they stay in place throughout the night, which can help signal to the baby that it’s time to sleep.
- Comfort: Sunday Sleep Bags are made from soft, breathable materials providing comfort and helping regulate body temperature.
- Durability: Sunday Sleep Bags often withstand more wear and tear than blankets, making them a practical choice for daily use and multiple washings.
Overall, sleep bags are designed with the safety and comfort of young children in mind, providing a secure and cozy sleep environment.
