I breastfed my first born exclusively for two years. After that, I slowly introduced her to formula milk because i wanted to wean her that time. My father in law told us to buy expensive formula milk but our kid preferred fresh full cream milk over warm milk. My husband teased him that we cannot afford buying expensive milk and so he was scolded real hard by FIL 🤣 But, our kid, our rule. Sorry FIL ❤️
