Sorry if this has already been mentioned and/or you've already made too much progress on the game to add this in without making an update, but I think that the new virtual families game should include a place on the mother's profile to show how many minutes she's nursing for, like in the virtual villager games. I think it would be handy because instead of just guessing when the baby will be walking and the mother would be able to work on her career, I could know exactly when that happens.
