Hi I’m using a love to dream swaddle tonight for the first time. It’s getting colder. My baby has a singlet, bonds jumpsuit and tog 1 sleeping bag. I have put a Muslin wrap over the top as per red nose guidelines - do you need the wrap to keep them from rolling or is the sleeping bag enough? They are already rolling to their side. 2 weeks old !!!

Most babies do not roll intentionally before 3 months; however, some babies do roll, especially to the side, at a very early age. This is not unusual.

Some babies do not respond well to wrapping/swaddling & prefer to have their arms free, which is often why they wriggle & end up on their side.     
Some babies like to touch their face or suck fingers when settling.
You could try settling your baby without any swaddle (or swaddle suit), or wrap with arms out. (as for 3 mth old)

Red Nose also has the following information about swaddle product/suits

The material of the wrap or swaddle should not cover the face or head, particular if baby sleeps with arms in different positions. If the item is too big for the baby, some zipped swaddle suits that enclose baby’s hands, have been shown to allow material to cover baby’s face and nose when baby raises their hands above their head during sleep. All sleeping attire designed to cover the baby’s shoulders should have separate neck and arm holes or should ensure that they do not allow the face covering if the baby was to move their arms in different positions.

Are you using the Love to Dream & a sleeping bag?
It is recommended to use a sleeping bag or a swaddle/suit, not both.
Are you using blankets?
Is your baby in a bassinet or cot?
Are you using the muslin wrap to try to prevent baby rolling?

Red Nose does not recommend the use of sleep positioners.
Red Nose does not recommend positional products such as anti-roll devices and items that fasten a baby into a sleeping position.
Products that restrict the movement of a baby or a baby’s head should not be used.

Always place baby on the back for sleep.
