Night time clothes chewing

[Guest guest]

This one has been going on for a year or more and is really frustrating me. My

daughter (ASD, 7 years, AC chelation approx. 100 rounds) chews all her pajama

tops at night time. Sometimes a T-shirt can be ruined in a night. She rarely

chews during the day time (unless she has a top with buttons or frills/ribbons

just crying out to be chewed!). At various times we have supplemented zinc to

the lb + 20 that is talked about (and I think even higher) and it doesn't seem

to make any difference that I can tell. It does come and go though and some

nights are much worse than others and there can also be a period of a few days

or so where she isn't chewing. Is it possible that this is worms??? It was

quite bad last week (new moon?) but seems to have settled down somewhat this

week. Yeast? We've done lots of OoO, GSE, biotin etc... and again nothing

seems to have an effect.

Thanks for any help,

Jenene.
