hi, I have 19 day old ds and have been doing switch nursing during cluster feeding. i am not sure when to switch though (havr brrn waiting for him to come off alone as have been advised never to end a feed myself) but after chat with nct lady today not sure this is right. should i switch when he stops actively sucking? it's hard to know when that is cos sometimes he seems to fall aslepp then gets going again. many thanks
