ditto on how to keep #1 occupied while nursing, lol!
We didn't have any issues on wanting to taste it, but we talked a lot about mommy's milk is for baby before born, and got a book about "our new baby" that shows mom bfing. He was 2 1/4 when DD was bron, and he nursed till 18 mo, so almost a year had passed and he didn't seem to really remember he used to nurse, which surprised me.
That said, he does from time to time ask to see the milk (ie wants me to squeeze the nipple to show him), even now (DD is 5 mo old) and unfortunately he is articulate enough to tell anyone he happens to think needs to know that "milk comes from mommy's nipple", and "she uses that big black machine on her nipple and it gush gushes and milk comes out in the bottle to save for later." So, on the subject of thinking it trhough, also think about what vocabulary you want your lo to use, and possibly tell the whole world.....
Good luck! And congrats!
