Just wondering how everyone does it really. For me I wind her every so often, but when she starts spitting out the teat I wind her again, rub her belly a little (gets really hard and full of milk, kind of cute) then try again. If she still spits it out I figure she's had enough. I also take an eruption of milk from Mt. Baby as a sign to stop for a bit, do some extra winding, and maybe try again in a minute.
