4 month old head bobbing?

[Aberdeen43]

I got my beardie from a pet store about a month and a half ago. I am assuming she/he is between 3 and 4 months old. Recently, my father has told me that she has started head bobbing (I am at college and he is taking care of her). So I'm taking his word for it as he hasn't been able to capture it on video. Could it just be that she has just learned this behavior and is doing it for "fun" until she knows what it is? Or could it be something outside her viv that is bothering her? She is active, alert, and always hungry (she eats a few supers and veggies in the morning, and crickets in the afternoon), and after posting my setup in a previous thread, I was told that was good too.

It`s perfectly normal for a bearded dragon to head bob at any age. She is probably just doing it at her reflection. If you have another bearded dragon, she is probably just doing it at that.
