Taking bottle away from 13 month old..

Hey, I would like suggestions on which sippy to transition to from a bottle. My son still takes a bottle at nap time and bedtime, and he still wakes at night... 🙄 But anyway, wondering if anyone had luck with certain cups? My son seems to have a hard time with certain sippy, the ones he does best with arent spill proof and obviously I need one that is for night time. I don't think he'll have a problem with me taking the bottle IF I can find a cup that he can drink good from. 🤔🤔🤔🤔
