from my experience of 2 - gave both babies with pertussis EES, a form of
Erythromycin, with no GI problems.  Baby 1 was 7 weeks, baby 2 was about 6
mo and unvaccinated.  Septra isn't rec under 2 mo.  I'd hesitate to give it
to a 10 week old.  Why is mom on Septra?  No reason she can't have
erythromycin.  I personally think the chance of overdosage from mom and
baby both getting Septra is far fetched and is another dumb reason to wean
even if temporarily.  It will have an effect on the BF relationship.
