Chewing

[Sherlock35]

Cross posting here too in the hope that someone can help

Hi

My 7 year old DS is currently on one of his chewing binges. He usually has something in his mouth like hair bobbles but he's started chewing on clothing too. He's put holes in most of his shirts and chewed through some sweatshirt sleeves

Can anyone recommend anything that I can give him to chew so he leaves his clothes alone?

Thanks

My daughter like chewy gems. The heavy duty treadle bangles are good and hold up fairly well.
