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.
She said: "I get a lot of phone calls around October time, with parents saying 'my child used to sleep through, why are they waking in the night now?' and it's because they're getting cold as October is the time when the temperature starts dropping at night but you don't start putting the heating on, so children start to wake.
"Once a child is in their light sleep cycle, it will wake them up if they're cold and it's those early hours of the morning, five o'clock sort of time when it's the coldest."
And in turn in the summer months, you might find your child is getting too hot and waking up because of it.
The expert urged parents to ensure their child's room was always the right temperature, which she claims is between 16 and 20C and to think carefully about how many layers a child is wearing or has on.
"Always follow the Lullaby Trust's website for guidance on how many layers to put on your child," she advises.
Jennifer goes on to share how parents who use thermometers or devices such as the Groegg thermometer and night light need to think carefully about where in the room they place them to correctly gauge the temperature.
She explains that if you place the device up high on a shelf, then because heat rises, the temperature up there won't be the same as the temperature at cot or bed level.
Similarly, if you place the device on the floor, it also won't be the same as higher up at your child's sleeping level.
"Measuring at cot level is key," she said, before adding one final piece of crucial advice: "Make sure that your child is warm enough, especially before the six-month mark, but even after that you've got to be careful of overheating.
"A cold baby is better than one that's too hot."
This comes after the expert explained exactly what time a child should go to bed depending on their age and when they need to wake up.
