According to a new study, experts are unnecessarily putting pressure on the parents by telling them that newborns must sleep the night.

Several baby advisers tell parents that babies should doze off 12 weeks. However, it was fond that only about a quarter of the babies start sleeping at night when then are 12 weeks old. About 16 per cent of the parents said that children at the age of 2 also wake up sometimes during the night.

A fourth of the children in the UK wake up at 6.30 am, which means that the parents do not get adequate amount of rest. A survey found that strict bedtime routine helps children sleep on time and the method is used by about 38 per cent of the parents.

About 20 per cent say they drive them round until they go to sleep. the most favorite timing for children in the UK to sleep is between 7pm and 7.30pm. Website Netmums, which conducted the poll, said, "Parenting gurus can set unrealistic expectations of babies' sleep patterns. This study shows there is no `one size fits all' solution."

The survey included a total of 11,000 people.
