The innovator, Maureen, created the magic sleepsuit to improve her babies’ sleep quality and duration. She is a pediatric physical therapist and a mother of four. It has become a patented swaddle transition product.

The magic sleepsuit is big and bulky; your baby looks like they are wearing a snow suit. The arms and legs are uncinched so your baby’s hands and feet can breathe. The weight around the arms and legs helps muffle your baby’s startle reflex.

Stages of Magic Merlin Sleepsuit

It is essential to know you need to stop using the sleepsuit once your baby starts to roll. It makes it harder for your baby to roll; they can get stuck on their stomach if they can roll over. Transitioning out of a suit into a sleep sack is the same as transitioning into a sleepsuit. Start using it at nap time, monitor the temperature, and then introduce it when the baby is comfortable at night.

One mom recommended starting with a nap to monitor your baby without disrupting sleep. You can start using it at night once you are confident with the magic sleepsuit use.

Safety and Recommendations

Regarding your baby’s safety, it is best to speak to a pediatrician. Your baby Merlin’s magic sleepsuit should be used in an empty crib. It has an open hands and feet design that helps regulate temperature for babies. If your house gets hot, you should buy the cooler cotton one.

Do not rely on the temperature of your baby’s hands and feet to know if your baby is hot. It’s common for your baby’s hands and feet to be cold if they wear the sleepsuit. Check your baby’s chest or neck; it should be warm, not sweaty or clammy.

Each Baby Merlin’s magic sleepsuit has undergone extensive safety testing and quality control inspections. The company is a member of Safe Sleep Guardians, which is dedicated to safe sleep for babies.

Appropriate Age and Weight

The Magic Merlin suit is available in small and large sizes. The small magic sleepsuit is for babies aged three to six months who weigh between 12 and 18 pounds. The large magic sleepsuit is for babies aged six to nine months weighing 18 to 21 pounds. The manufacturer offers a free Visual Sizing Assessment, which is very easy. Email [email protected], and they will provide you with their guidance and assessment on size.


The effectiveness of the magic sleep suit depends on the proper timing when introducing it to your baby. The magic sleepsuit should be introduced at three months when the baby needs more sleep space. Parents attribute improved nap and night sleep to the magic sleep suit. They say it soothes the baby and tames their Moro reflex, the startle reflex. The Moro reflex is an instinctive response present in infants, and it involves the baby suddenly extending their arms and legs and bringing them back to their body in a hugging motion. It can be triggered by loud noises, sudden movements, or other things disrupting the baby’s sleep.

It is cozy without restricting movement, durable, and lasts long. It provides a snug and comfortable environment that reduces the Moro reflex, which further helps you establish good sleep habits and maintain a consistent nap schedule.

A mom talked about how her baby naps for just 30 minutes maximum and sleeps for just about 5 hours at night and won’t sleep back except if the baby is in bed with her, but after she decided to get a magic sleepsuit for her child, her child naps for about one and half hours and sleeps for about eight and half hours at night.

The double zippers make for easy diaper changes, though you must bring them out of the sleepsuit. The open feet and hands make temperature control easy.

Safety Guidelines

Safe sleep in babies is sensitive, and for good reason. The American Academy of Pediatrics provides a guideline for safe sleep. According to the Merlin sleepsuit company, the AAP recommends that baby Merlin’s magic sleepsuit be used with the ABC’s of sleep (Alone, Back, and Crib) while also following all AAP guidelines for safe sleep.

It is essential to note that you should stop using the Merlin suit when your baby starts rolling over on their own and needs more freedom of movement. That sometimes happens around seven months old.

The recommended room temperature for babies sleeping in a Merlin suit is between 68 and 72 degrees Fahrenheit. It is best used when your baby is in the crib.


It is suitable for afternoon naps and nighttime sleep. It also holds up for a long time. You can sell, donate, gift, or use for your other children.

Practical Considerations

You wear your magic merlin suit like a button-down or zipper full-body romper or sleepsuit. You unzip two full-length zippers on both front sides of the sleep suit, put their arms and legs in, and zip the whole thing back.

It is easy to wear and remove. It is suitable for machine washing, tumble drying, and hanging to dry; do not iron. A tip you may find valuable so the arms and legs dry faster is to dry the suit till it is 90% dry, then change the sleepsuit inside out to dry completely.

A mom said the magic sleepsuit worked magic for a first baby, but her second baby didn’t like it, but he has good sleep habits. This shows that one product doesn’t work for every baby, but if you are a tired parent sleep-training your baby, you have nothing to lose.

Potential Drawbacks

It may be hard to transition your baby out of a sleep suit. Your baby may also struggle to roll when wearing the sleep suit. The baby Merlin magic sleepsuit is supposed to be easy to transition out of. When your baby starts to roll, you may want to transition it to sleep on their own.

The magic sleepsuit should not be for co-sleeping or any sleep positioners. It can be too warm and hard to transition out of.

Considering the drawbacks, there is only a little to discuss except the price. The sleep suit costs about $40. OneStepAhead has an affordable sleep sack from $13. The magic sleepsuit is durable, so you’ll sometimes find them in donation, thrift, and consignment stores.

Comparisons with Other Sleepwear

Some moms have tried using sleep sacks from other brands, and they were too hot or not snuggly enough. The Magic Dream Sack Walker is an excellent transitional product. The Ikea sleep sack with a double layer of cotton and terrycloth is also a good product.

Final Thoughts and Recommendations

The magic sleepsuit is a helpful tool to transition the baby from swaddling to being able to sleep. You are required to stop using the sleepsuit when the baby rolls over. Use the magic sleepsuit according to AAP guidelines. Many moms say their baby fell asleep all night using this sleepsuit. If your baby is between 3 and 6 months and wakes up frequently at night and you wake up tired, you may want to try the magic sleepsuit. It is designed for back sleeping and comfort.

Make sure you keep a safe and comfortable sleep environment. If your baby does not settle into the baby Merlin’s magic sleepsuit on time, you have nothing to lose, and if it works for you, then you and your baby will sleep well.
