If you've not been feeding at night up to now I would just resettle without a feed. She will protest but after a few nights she should stop waking to ask for BF.
I wouldn't bother with other milk either. And defo wouldn't start a bottle at this age. In the UK we are advised to stop bottles by 12mo. Does she have any milk in cereal?
The BFing is good for immunity as well as nutrition so I would just keep offering and let her take what she wants. I bet you would be surprised how much a 1yo can take in a 1-2min BF anyway.
