Re: is she weaned??
Two of my dds weaned exactly the same way...and I cried each time. I wasn't ready but apparently they were. Milk does change in taste/volume during pregnancy.
If you were really set on nursing for longer, tandeming you could offer ... or you could wait until after the baby is born when the special difficulties of pregnancy are gone and see if she wants to start nursing again. I never did w/ mine but I know others who have gone back to nursing after several months off.
