There are numerous factors that can have an impact on the length and quality of a child's sleep - from the sounds in the house to what time they woke up that morning and how many naps they've had.
But an expert has also warned that temperature in a child or baby's bedroom can make a massive difference, explaining that thermometers are often not accurate.
Jennifer Robinson, a gentle sleep consultant who has her own business called the Happy Sleep Coach, told The Mirror that temperature is a "huge" factor when it comes to sleep.
