According to a new study from Finland, sleep problems among infants are very common and normally improve by the time the child reaches the age of two.
The study, carried out by the Finnish Institute for Health and Welfare (THL) and the University of Turku, found that large changes take place in the sleep of infants during their first two years: the time taken to fall asleep reduces to an average of 20 minutes by the age of 6 months, and by the age of two small children wake up are on average only once during the night.
At the same time, the total amount of time spent sleeping reduces to around 12 hours per day as daytime naps get shorter and the child’s sleep becomes more stable and more consistent.
However, there are large individual variations in the quality of sleep of babies and toddlers, and many parents are concerned about whether their child’s sleeping patterns are normal or not. Around 40% of the parents of eight-month-old children who participated in the study said that they were concerned about their child’s sleep.
The study contains data on approximately 5,700 Finnish children, and information provided by their parents. The primary goal of the study was to investigate how infants’ sleep develops during their first two years.
“Up until now, we have not had any reference values for good infant sleep that are based on large data sets,” says Research Manager Juulia Paavonen from THL. “Now we know that the individual differences are very large, and that patterns relating to falling asleep, waking up, staying awake at night and sleeping rhythms often develop at different rates.”
The study also sought to examine how large the individual differences in sleep among infants can be while still falling within the boundaries of normal child development. This would save parents from unnecessary worry and would help to focus interventions on genuine sleep disorders.
“Those children whose quality of sleep is clearly different from the average would probably benefit from situation assessment at, for example, the child welfare clinic. There are many tools available for reducing children’s sleep problems,” Paavonen says.
According to Paavonen, it is difficult to give a general recommendation on the total amount of sleep required, although sufficient sleep is certainly important for a child’s well-being. The amount of sleep required depends on many factors.
“It is important to look at the child’s well-being as a whole.”
If it takes longer than 40 minutes for the 8-month-old child to fall asleep, it is best to discuss the matter with a pediatrician. The same applies if a 6-month-old child normally wakes at night three times or more, or if the child stays awake at night for particularly long periods, which would mean over 60 minutes for an 8-month-old baby, over 45 minutes for a 12-month-old, or over 30 minutes for an 18-month-old.
“If the parents are very concerned about their child or their own ability to cope, help should be sought even before these levels are reached,” Paavonen emphasizes.
