Tips on night weaning (formula fed)

I have a 7mo that still feeds 2x a night. I think we’re ready to drop to 1 feeding or even none if possible. She sleeps total 12hrs so she goes about 4-5hrs between.

She used to just do 1 feeding but lately has been 2. I try to give her as much milk during the day but at some point she just refuses cause shes full.

Just need some tips on how to go about it. I dont really want to let her cry.
