According to a new study, there is good news for those parents, who are not able to sleep properly, because of their new born babies.
The research says that majority of babies start sleeping whole night when they reach 2 and 4 months of age.
The study also said that it may take some time for the babies to match the sleeping schedule of the family.
After first four months of their birth, infants sleeping pattern changes rapidy, reported the study.
Jacqueline Henderson, study author, said, “Given this, we examined another definition of 'a night's sleep' that better suits family members' sleep requirements, from 10 p. m. to 6 a. m. We found infants are most likely to begin sleeping during this period at age 3 months, with over 50 percent doing so at five months”.
For the study, Henderson and team took parents of 75 full-term infants who gave their consent to complete sleep diaries for six days every month.
The verification of the information in the sleep diaries was done by using a video sleep study.
The researchers noticed that by 5 months of age, over 50% of the children who participated in the study were sleeping for the same hours as their parents.
The findings of the results have been published online in the Oct. 25 issue of the journal Pediatrics.
