I'd either do one each end of the afternoon nap and count it as one full feed, or do a DF at 8ish, or express and offer milk as the drink with solids, rather than water. Not sure if you do a BT bath, but when DS was refusing to eat at BT, I hopped in the bath with him and he was happy to feed in there
That lasted about 2 weeks, then he'd happily feed in the normal feeding spot at BT and go down without a fuss.
