This is from the LLLI Professional Liaison Program Newsletter-Volume I, Number 2: Clampdown Bite Reflex Several sources have reported a possible connection between tonic bite, or clampdown reflex, and the mother's diet. No studies have been done, but there are anecdotal cases where the mothers usually had a family history of allergies and/or birth was difficult, there was usually some separation of mother and baby and sometimes bottles had been given. Most of the mothers did not like milk, but drank it during pregnancy. Their babies tended to clamp down with latch-on and improved when dairy products were ommited from the mother's diet. Just a thought. Diane Karnbach, LLLL
