my daughter is 3 years old she suddenly stopped drinking milk is there anything serious issue with this

A. A lot of kids don’t like milk and very honestly milk is not that important also in this age if the child has proper meals and proper proteins otherwise and dairy products and general then there is no need to give milk you can include more of curd buttermilk as well as you can give other dairy products if the child doesn’t want to have milk and it is not at all a serious issue
