My Sleeping Baby is Toronto’s ONLY supplier of the Magic Merlin Sleepsuit!

The Magic Merlin Sleepsuit ™ is an innovative baby product that helps with the transition from the swaddle and provides babies with a cozy, calming, and safe sleep environment. The Magic Merlin Sleepsuit is designed for babies who have started breaking out of the swaddle or have become too big for swaddling, yet still need that warmth and contained feeling to aid in their sleep.

Many babies in the 3-4 month-mark still have some of their startle reflex.  This can make the transition to a traditional sleep sack very challenging.  By muffling that startle reflex, the Magic Merlin Sleepsuit serves as a fantastic “halfway point” between the swaddle and the sleep sack.

This Magic Sleepsuit is also very helpful for babies who have started rolling as it keeps babies positioned on their backs until they are efficiently rolling both ways.

The Magic Merlin Sleepsuit is designed to be used in the crib for back sleeping only. The Magic Sleepsuit helps eliminate the need for blankets and other loose bedding, which is consistent with many recommendations to prevent SIDS.

If your baby has any medical or developmental conditions, please consult with your physician before using this or any product in your baby’s crib.


Ideally, you should wait until your baby is 3 months of age to start using the Magic Sleepsuit.  However, it really depends on the size of your child. The Magic Sleepsuit should fit comfortably, yet be snug enough so that the baby feels secure in the suit. There is some overlap between the small and large sizes with guidelines as follows:

3-6 months
12-18 lbs

6-9 months
18-21 lbs

If you are unsure what size to get, we recommend getting a size small if your little one is wearing 3-6-month clothing.  Get a size large if your little one is wearing 6-9-month clothing.
