Cow milk contains high PRSL load, which is not recommended for babies. So, a big NO for cow milk. Do not give loose milk, it has to be pasteurized. Cow’s milk is meant for calves to grow and not humans. My Pediatrician recommended me Farex; definitely, a better choice as compared to Lactogen or cow’s milk especially in children with lactose intolerance. I started with Lacto, but it caused constipation. So, I shifted to Farex. You can also take suggestion from doctor.
