I ♥ you! I nursed until 34 months. Had to stop one weekend when the lady at the pizza shop said no, there was no egg in the pizza. When I questioned her again after - since I know I tasted egg wash; having been without for 3 years I just KNEW - she said, oh, yeah, well we just brush it on the top off the crust. It's hardly any. She was the owner, too, turns out. :(
Anyway, we were on vacation and told DS he couldn't have it that night since I inhaled 3 pieces (DS ate the cheese but refused the crust, another thing that tipped me off), and then DH and I decided it was as good a time as any to wean. Blah. I would have kept going otherwise.
