Sleeping Bag Instructions


  1. How do I know when to transition my baby from swaddling?
    When your baby shows signs of breaking free from swaddling or rolling over, it's time to transition into a sleep bag.  To make the transition easier, we recommend gradually transitioning your little one to using the Classic Sleep Bag.  You can do this by swaddling your baby for a few nights with one arm out, then both arms out of the swaddle.  Your baby will still have the secure feeling of the swaddle while gradually adjusting to having his arms free, making the transition to a sleep bag smoother.
  2. What is the TOG rating for the Classic Sleep Bag?
    TOG rating for the Classic Sleep Bag is 0.5.
  3. Do either the Classic or On The Move Sleeping Bag come in different TOGs or fabric weights?
    Currently, our sleep bag range is available in a Light (0.5 TOG) & Mid-Weight (1.0 TOG). Stay tuned for additional warmth levels as we continue to grow our range. Feel free to sign up for our newsletter to learns about new warmth levels and cute prints as they become available!
  4. What's the difference between the Classic and On The Move Sleeping Bag?
    Both styles are made of the same soft 100% cotton knit and have the same TOG rating (0.5 TOG). Additionally, they BOTH feature adjustable shoulder snaps, a double zipper, and a seat belt slot. However, the Classic Sleep Bag is our small bag for babies 0-6 months. It does NOT have the convertible 2-IN-1 walker design feature. The On The Move sleeping bag comes in size Medium (6-18 months) and Large (18-36 months) bag, designed specifically for older babies as they transition into a walker and need the added mobility.
  5. What is a TOG rating?
    TOG stands for Thermal Overall Grade. It is a unit of measurement used to calculate the thermal insulation of a product, commonly used in the textile industry (quilts, duvets, and comforters). It indicates the degree of warmth you should expect from your swaddler. The higher the TOG, the warmer the garment. To help caregivers understand what TOG fits your needs, we have recommended guidelines for each TOG. Please see the “What To Wear Under Your Sleep Bag” chart.
  6. Is the Classic Sleep Bag machine washable?
    Yes, all of our sleeping products are machine washable.
  7. What material are the Classic Sleep Bags made of?
    Ergobaby's Classic Sleep Bags are made of 100% ultra-soft cotton fabric.
  8. How long can I use the Classic Sleep Bag?
    The Sleep Bag allows for use up to about 6 months! Once baby can roll, they are likely ready to grow out of a swaddle and into a sleep bag. The Classic Sleep Bag has two snap adjustments at the shoulder to grow with baby up to about 6 months.
