Mera baby Kuch BHI Pani Nahi pi Raha hai please suggest me

A. Hello good morning !! check if baby suddenly rejecting feed, milk then check temperature ,or any other discomfort (constipation,gas...). Mild fever, motions, hard swollen gums, reddish gums, cranky, rejecting feed then might be in teething stage.. Due to swollen gums,they will be cranky, reject feed so soothe with soothers, teethers,give finger foods,warm soups, semi solid foods,fluids which ease from gum pain.
