Sleep is a Developmental Milestone.
Babies who are learning to crawl tend to wake more frequently in the night than they did previously, twice each nights, as opposed to 1.5 times per night, on average.
It’s a reminder that babies have their own very good reasons for waking in the night, even if those reasons aren’t always immediately obvious to their parents.
In the first two years of life, babies are really consumed by motor
development and motor changes A baby is more easily roused from sleep while their brains are busy trying to solve a fascinating new puzzle: the mechanics of learning to crawl.
A newly mobile baby who is experimenting with increased independence during the day may crave added reassurance from her parents at night.
It is normal for a baby to be gaining independence and be clingier at the same time.
Often when a crawling baby wakes the night, he/she is on hands and knees, rocking back and forth.
It can be stressful when you hit this kind of developmental milestone.
The night waking generally lasts about three months after a baby starts crawling.
