#asktheexpert my lo is 13 months old. he have been on bm and fm for n year but now when we tried to introduce cow milk or buffalo milk to him in very small quantities mixing after dilution and making kheer initially, he got loose stools. we tried at different intervals and for different brands too but same output. He stays fine with lactogen and bm. pls suggest what to do and how to stop fm and start normal milk.
