Romper takes a look at when and why babies regress into poor sleep.

According to Brooke Hohenadel, a London, Ontario-based sleep consultant for Bedtime Beginnings, infant sleep regressions can be characterized by a sudden change in sleep/wake patterns. In an interview with Romper, Hohenadel explains a regression as, “a baby who appears to have conformed to a ‘healthy’ sleep routine, with few to no nighttime wakings suddenly experiencing an increase in wakings, sleep refusal, and desire for parental intervention.”

But the “10-month” sleep regression is not actually limited to the tenth month, points out Marietta Paxson, sleep consultant at Little Dreamers. Paxson tells Romper that the phase is sparked by gains an infant suddenly makes in physical milestones, like crawling and pulling up, as well as language absorption and the emergence of teeth. Since these vary widely from child to child, sleep regression can actually occur anytime between 7 and 11 months.
