What are normal sleep patterns for age?
When discussing “sleep normals” it should be remembered that there is some variation between different infants, and different ages. It is best to seek our individual advice to determine if your infant is in a normal range.
A sleep problem is any sleep pattern that interferes with the refreshing nature of sleep or that appreciably disrupts the sleep of others. A sleep problem in young children also can be defined solely by the context of parental expectations – not all problems are abnormal, nor do they all need treatment. (5)
The normal sleep patterns change at each age. The newborn sleep pattern is very different to the baby at 2-3 months, 5-6 months, 7-10 months, and 10-12 months, and beyond (1, 6, 7).
At our practice we assess your baby/child’s sleep patterns, and put them in the context of research into “normal infant sleep,” and how this is affecting your baby’s and your health.
What affects sleep?
Sleep is influenced by numerous factors. These can include gestational age, environment, culture, settling skills, habits and other factors. In the infant this is all complicated by unique anatomy and an immature nervous system (8).
Certain medical conditions (e g. cerebral palsy, autism, and other developmental disabilities) have a higher incidence of sleep difficulties. Acute illnesses and teething can affect sleep (9), but this effect is usually short term in nature.
