	Also consider glucose-6-phosphate dehydrogenase (G6PD) deficiency.
G6PD deficiencies are common in SE Asia, as are the thalassemias.  There
is chronic neonatal jaundice in some cases, and it may be induced by in-
fections or by the administration of certain drugs.  The fact that a pre-
vious female child experienced difficulties makes G6PD an unlikely hypo-
thesis, however.  In the first place, the G6PD gene is X-linked, which
means that boys are much more likely to experience trouble than girls.
Second, all the known mutations are recessive, which would mean that in a
female child the normal copy of the X chromosome should compensate for the
mutated one.  Still, it's worth considering.  Maybe the father's G6PD 
and/or hemoglobin status should be checked, too.
