How much sleep do you lose in a month?
Parents will lose an average of 16 nights of sleep, per month, in the first three years of their child's life, a survey has found.
Researchers found that mums and dads have to struggle through broken night's sleep from the end of pregnancy through to their child turning three.
Common baby and toddler stages such as teething, bad dreams and the transition from cot to first bed will add to the total of days and hours of sleep lost during this time.
The survey by Worlds Apart also found that parents will get up for their child on average three times a night in the first three years.
One in seven parents in the survey agreed that between the ages of two and three was the worst when it came to getting a full night's sleep.
And when their child was two to three years old, parents from the survey reported they were woken up an average of three times a night; only one less than with a new born to two year old toddler.
Losing a dummy, being scared of the dark and hearing other children walking around were also found to be regular reasons for parents being woken up at night.
