Hi K.,
Awesome that you're still nursing!
I do wonder why you would switch your human child from human milk to cows milk though. If you're nursing on demand and giving your child healthy food options there is no need to measure your quantities of milk. Nature provides the right combination of stuff in your milk for your child, just like it does for cows to nurse their calves.
The World Health Organization recommends nursing till at least age 4. No offense to the woman who suggested weaning your daughter she doesn't know what she's talking about for proper nutrition for a child. Her reasoning is idiotic, "is so dependant on Mom". A baby is supposed to rely on her/his parents!!!! Nursing has been proven to do nothing but create a child that feels secure and loved and able to go out securely into the world knowing that her/his parents will be there need be.
I don't think there is a real science, nurse and provide food when you eat for her. Fresh fruits, veg and grain should be there to taste, if she wants.
