Greetings It is common and developmentally appropriate for a 2-year-old to refuse a bottle as they transition toward solid foods and open cups. There is no medicine used to encourage bottle feeding, as the primary goal at this age is typically to phase bottles out entirely. You might try offering milk in a colorful 360-degree cup, a straw cup, or a standard open cup to make drinking more engaging. Focus on providing a balanced diet of solid foods, as most toddlers this age should get their primary nutrition from meals. If you are concerned about her hydration or calcium intake

Nothing to worry. At 2 years, bottle feed is not necessary at all. In fact, it’s better to avoid bottle at this age. You can give milk in a cup or glass instead. If she is eating normal home food and taking some milk by cup, that is perfectly fine. No medicine is needed. Don’t force feed—offer small frequent feeds and keep it stress-free.

This is normal only in this transition period Stop giving initially in day time and allow giving in night time and gradually decreased the frequency in day time also

Go slowly over 3-4 weeks... reduce breast feeding first in a day time .. reduce duration also ..if excessive Cry then give comfort by Hug and  entertainment to divert mind

At this phase, try to minimise giving direct breastfeeding as only on extreme demand. Try to make the solid meals more fun and engaging and more satisfying. Give milk in cups or straw cups. Try sternly refusing breastfeeding everytime the baby asks for it and making it clear that it is not allowed.
