We did same as above - 2 BF's at 13 months (was 3), 1 BF at 14 months, weaned fully at 15 months. Sippy with cow's milk at all meals from 1 year on.
Feeding schedule:
7:20 breakfast
12:00 lunch
3:30 snack
5:00 sometimes a small snack if too hungry to wait for dinner, and I like us to all eat together
5:45 dinner
DD is 17 months old, and we've been doing this since 1 year.
Tried a morning snack which dd liked, but then she wasn't interested in lunch, and she didn't seem to miss it when gone.
