So DD will be nearly 12 months? I'd say try cows milk for her lunch time drink.
You have done an excellent job bf this long and its great you want to keep going!
I started weaning DD off some feeds in a similar situation at 9 months, but because of her age I went to formula.
She was having cows milk on her cereal at 8 months, and then started switching her drinks to cows milk at 11.5 months because I knew she hadnt had a problem with it.

So maybe (if you havent already) try her on a little with her breakie and see how she goes.
