Lisa - as far as I am aware, tandem nursing amongst the indigenous population in Zimbabwe is never practised. The older baby/child is weaned on the turn as soon as the mother discovers a new pregnancy because it is believed that the milk turns "poisonous". Sometimes the nursling is even given an emetic so that s/he will vomit up the last milk ingested. I have had two clients who delivered their second babies in a private clinic and nursed their older toddlers during visiting hours. The first time the nursing staff were shocked to the core, the second time they were a little more accepting - I guess we can slowly educate people, one mother at a time ..
