What worked for me was mixing the full cream milk slowly into the formula, like maybe 70% formula 30% fresh milk first, then gradually shift the ratio over a week or two until she is fully on fresh milk. For the bedtime bottle habit, you can try switching to a cup instead so it feels like a different routine to her, and maybe move the milk to earlier in the evening so it is not the last thing before she sleeps. Just take it slow n easy
