Head banging

Anyone else's baby started head banging? My 10 month old will repeatedly hit herself in the head with her hand or try to bang against something when trying to get her down for a nap or bedtime. I've been finding this quite upsetting and worrying. Anyway I've come across this article that I found very helpful and reassuring and thought I'd share just incase anyone is experiencing the same thing! https://www.babycenter.com/toddler/behavior/head-banging-12-to-24-mo_11554
