Weaning from nighttime bottle?

Help! I would like to start to wean my LO from her nighttime bottle , it’s the only thing that gets her to fall asleep and she o my drinks it at nap time and bedtime she doesn’t drink out of it during the day but at bedtime I’m constantly getting up every few hours as she wants a new bottle, I know her pediatrician suggested to start weaning but I don’t know how or where to even start? Have any of you weaned your little ones yet ? And tips and tricks you recommend??
