Not taking bottle before bed

Me

My daughter for the past month is now not finishing her bed bottle(I’ve been feeding her in her sleep a few hours after she goes down just so she won’t wake in the night)

She used to take 7oz before bed no problem and now she barley takes 2. She has dinner at 5 and bottle at 6:30/7. I’m not sure why she now doesn’t want it and I don’t want to keep giving her a dreamfeed. Just looking for any insight please.
