I just made a gruit ale based on a beer from Cambridge Brewing Company, recipe courtesy the brewer there.  Among the many ingredients was jasmine blossoms.  The recipe called for 40g total, 25g at 5min and 15 at flameout.  These are the quantities for dried jasmine.  If you use fresh, then just double the weight (i.e. 80g).  We ended up using only 15g at the flameout because that was all we could get our hands on without buying a ridiculous quantity.  Hope that helps get you started and gives you a range to work with.  And by the way, Congratulations on the daughter!!!  Wish you the best.
