Our little one likes to be warm and will wake easily when cold. We have found that when swaddled with a long sleeve pjs on she often isn’t warm enough. During the day we often use blankets where we can supervise she sleeping. What would you recommend you use to keep her at night time?

How old is your baby?
Is your baby rolling yet?

A blanket can be used if baby is staying covered by the blanket & that it sits no higher than chest - to reduce the risk of head/face covering.
Add or remove bedding/clothing during cooler or warmer weather.
Always use light weight blanket tucked in firmly (not too tight)
