Jennifer, It couldn't hurt to eliminate dairy and see what happens. I haven't done a literature search on the relationship between cow's milk protein (CMP) and GER in awhile, so these are not the most current refs, but they give an idea of the research. ". . .gastroesophageal reflux was associated with, and probably caused by cow's milk allergy, in 85 of 204 cases (41.8%). CONCLUSIONS: Considering the frequency of this association, patients younger than 12 months old with symptoms of gastroesophageal reflux should be carefully examined to determine whether this disorder is primary or caused by cow's milk allergy."

Trying different bf-management techniques might help -- nursing on one side for x hours at a time, having baby nurse 'uphill', etc. Warmly, Margaret Longmont, CO *********************************************** To temporarily stop your subscription: set lactnet nomail To start it again: set lactnet mail (or digest) To unsubscribe: unsubscribe lactnet All commands go to [log in to unmask] The LACTNET mailing list is powered by L-Soft's renowned LISTSERV(R) list management software together with L-Soft's LSMTP(R) mailer for lightning fast mail delivery.
