Stop na sa milk - 15months

My 15 months old baby girl is now refusing to drink milk. 🥺 Unlike before, she only consumes 14oz of milk per day for almost a week now tapos sapilitan pa. Instead, she always ask for water, consuming 35-42oz per day aside from the water she's drinking in glass after meals. Any advice po? Is it ok na bumutaw na sya at this early age? #pleasehelp #advicepls
