[tri-med] Re: tri children and reproduction

Shelby is in EI because she was born at 5 months and weighed only around 1
pound - there are many premature babies placed into EI.  She was tested for
T-18 at birth and she is NOT an 18.  I don't know the specifics about
genetics, but I do know for sure that Shelby tested negative for T-18 and
that her mother, Nikki, is a partial T-18.

(wife of Bob; mother to Rachel 2-1/2  (T-18), Jillian 1-1/2 (our China baby)
and Ian 6 months)
