Is it normal for kids to go through a phase of biting/chewing on everything?
I remember when I was about 7-9, I went through this phase where I had this feeling of wanting to bite on things with my front teeth and chew on them. It became such a habit. Anything that looked tough or rubbery I'd want to bite on it. I'm reminded of it now cos I'm looking through some of my old things and a lot of them have small chunks bitten out of them. Things like books covers, the rubber grip of my tennis rackets, anything leather, etc.
