pica eating odd stuff

Has anyone had problems with this .

My son who is adhd used to eat things ranging from fluff ,wood,stones ,dirt, elastic bands,loom bands, snails and all sorts.

His favourite seemed to be fluff ,wood and elastic bands.

He was always a good eater as a young child ,but has got very fussy as a teenager .

Started when he was about  3 and went on until about 7 or 8 .

He would be very secretive about it ,but would often see him pop some thing in and race over to get it out .

He is 13 know and as far as i know doesn't any more ,but does talk of eating fluff as a child with fond memory.

Thought i would put this up as maybe helpful to someone out there going through the same.
