Ok the baby's not here yet, but I think things are going that way. Ds finished bf-ing at Christmas when he was just over 2 years. He didn't seem to worry about finishing, he essentially self-weaned.
Now the baby's on the way, he is getting more and more interested in milk and feeding again (friends are having babies and he is fascinated by them getting milk). I have always told him the milk's gone now, and he is satisfied, but he also says that he could drink the milk if it was there...
So I am thinking about what happens when the baby arrives and wondered about other's experiences. I didn't really want to tandem feed, but have no issues about letting him feed again. I just don't want him to be jealous when the baby feeds, and wonder about him taking food from the baby.
