Getting your baby to sleep through the night is every parent’s goal, but don’t blame yourself if your little one is keeping you up. A study, published in the journal Pediatrics, asked 400 Canadian mums how long their babies slept without waking in the night. Defining six or eight hours’ uninterrupted sleep as ‘sleeping through the night’, researchers found that at six months, 62.4 percent of babies slept for six hours, rising to 72.1 percent by the time they were a year old. Eight hours’ sleep proved elusive, with only 43 percent of babies managing this at six months and 56.6 percent at a year. First study author MarieHélène Pennestri says the aim of the study was to “lower guilt” in parents, adding that more realistic expectations about babies’ sleep patterns may help parents cope.
