A new survey has revealed that parents across the UK will face a 7.03am wake-up call on Christmas morning. The research, by thortful.com, asked British parents about their children's sleeping habits across Christmas eve and Christmas morning, finding that 33 per cent of parents said their kids can wake them up as early as 6am. Those in Gloucester say they have the earliest wake up times, with their kids waking them up at 6.10am on Christmas morning. On the other hand, those in Oxford are treated to a lie-in with their children not waking them up until 7.37am It was revealed that the average time children wake their parents up on Christmas morning is 7.03am. However, 33 per cent of parents said their children can wake them up as early as 6am and almost one in six said they usually get woken up from 5am. To no surprise, excitable children waking their parents up has resulted in almost half of parents admitting to sending their kids back to bed after being woken up on Christmas morning. Furthermore, 39 per cent say their children have woken them up in the middle of the night between Christmas eve and morning. Looking around the country, those in Gloucester say they have the earliest wake up times, with their kids waking them up at 6:10am on average.
