milk allergy in infants: A prospective study. Journal of Allergy & Clinical
Immunology 1996; 97:822-7.

Thanks to Kathy, Pat and others for the Christmas stories. One year I
rented a pump to a mother being discharged, without her baby, at 5 pm
Christmas eve. (ARRGGHHH!) This year my newspaper delivery-person needed a
pump for her sick newborn - my Christmas gift to her was free rent for the
time her baby was hospitalized. Merry Christmas to all who celebrate this
holiday; Happy Hannukah to others; Peaceful Winter Solstice to some; and
Happy New Year too!
