Is head banging normal?
Yes, occasional head banging or rocking at bedtime is very common and usually a normal, harmless way young children soothe themselves to sleep.
It typically starts around 6-9 months, peaks between 18-24 months, and most children outgrow it by age 5.

Based on established pediatric sleep guidance and case-series/clinical review literature describing typical patterns of rhythmic movement behaviors in children, rather than large randomized trials.
What the evidence says
Head banging, rocking, or head rolling at bedtime is a common, usually harmless habit in babies and toddlers. Children often do this because the rhythmic motion is soothing and helps them fall asleep. It tends to start around 6 to 9 months of age, can peak between 18 and 24 months, and most children stop by age 5.
If your child is healthy, developing normally, and only does this while settling for sleep, you usually don't need to worry. It can cause minor redness or bruising on the head, but this is rarely serious. Making the sleep space safer, like moving the bed away from walls and removing hard objects nearby, can reduce bumps and noise.
A small number of children, about 1 percent, have a more intense version called sleep-related rhythmic movement disorder, where the behavior badly disrupts sleep or causes real injury. Head banging is also seen more often and more intensely in children with autism or developmental delay, though it can happen in any child.
Check in with your doctor if the head banging happens a lot through the night, causes injury, is linked to snoring or daytime tiredness, or if you have any concerns about your child's overall development.
