When Is Infant Sleep Regression?

Sleep regressions are common at several ages, including 4 months, 8 months, and 18 months. While other issues can cause disruptions in a baby's sleep habits, you can distinguish a regression from other sleep disturbances based on when it happens, how long it lasts, and whether there are any other issues.

How do I know if my baby is having a sleep regression?

More frequent night waking. Trouble falling asleep at bedtime. Increased fussiness or crankiness. Suddenly resisting naps.

What age do babies have sleep regression?

Sleep regressions can occur at any age, including 4 months, 6 months, 8 months, 18 months and 2 years. The 12-month sleep regression occurs at or near baby's first birthday, though some children begin regressing at 10 or 11 months.
