Hi, My 8 week old started to show signs of rolling but still inconsistent and startle reflex still strong. Is the merlin sleepsuit approved for transitioning? baby will feel that he’s still being swaddled but arms out. https://www.magicsleepsuit.com/collections/frontpage/products/blue-magic-sleepsuit?variant=196313862

Red Nose recommends that once baby is rolling they need to be moved to a cot & cease wrapping.
It is important that baby has the space of a cot & arms free to roll safely.
Many babies do not usually transition from a wrap. What type of wrap are you currently using?
A safe sleeping bag, with arms out, may now be appropriate.

Infant Sleeping Bag

An alternative to wrapping is to use a safe infant sleeping bag; one with a fitted neck and armholes that is the right size for the baby’s weight. Clothing can be layered underneath the sleeping bag according to climate conditions.

Most babies will be rolling over by 4- 5 months - many earlier. This is very normal as babies grow & become stronger.
Many babies then prefer to sleep on their tummy.

This is not something that needs to be stopped. It is important to make his new environment as safe as possible.

Ensure that the cot mattress is firm & flat & there is nothing soft or loose in the cot.
Always place baby on back to sleep.
Increasing tummy time when awake.

Red Nose has the following information now that your baby is starting to roll.

If you are using a bassinette, it is time to transfer baby into a cot as soon as they first show signs of being able to roll.
Give baby extra tummy time to play when awake and supervised as this helps baby to develop stronger neck and upper body muscles which in turn enables them to roll back over.
Make sure that baby is on a firm and well-fitting mattress that is flat (not tilted or elevated).
Make sure that baby’s face and head remains uncovered (do not use lambswool, doonas, pillows, cot bumpers or soft toys)

As babies grow and develop they become very active and learn to roll around the cot.
At this time, continue to put them on the back at the start of sleep time, but let them find their own position of comfort.
By this stage it is not necessary to wake during the night to turn baby over to the back position

Do not use any devices designed to keep baby in a particular sleep position.
