zinc for picca, anything else? please help

[Guest guest]

My daughter is 41 months old and still mouths everything. It is so bad

that she puts holes in her clothes at times, chews her books.... . We

started zinc 2.5 months ago and are at 90mg with the syptoms still

present. We do a lot of oral-motor activities too since she craves the

oral motor input (she has very poor sensation in her mouth area). Any

other suggestions besides time?

Thanks,

Kathy and
