The Magic Sleepsuit is designed to be introduced when babies are transitioning out of the swaddle and into the crib which is usually around 3 months of age.
The Magic Sleepsuit is designed to be used after the swaddle, not with a newborn as a swaddle alternative. At 0-3 months, when babies are typically swaddled, the startle reflex may be too strong to have sustained success with the Magic Sleepsuit.
The other very important issue with using the Magic Sleepsuit with younger babies/ infants is the sizing of the Sleepsuit, because for safety and effectiveness the Magic Sleepsuit needs to fit properly. (Please see FAQ - “How do I know if the Magic Sleepsuit fits my baby properly?”).
When you are ready to try the Magic Sleepsuit, we encourage you to send us a photo of your little one wearing the Sleepsuit to firstname.lastname@example.org. We can do a visual sizing assessment and give you sizing input.
