My LO is 13 mths old and recently has been pooping 3-4 times a day at caregiver's place. He is ok at home ( once a day ) We've recently started him on whole cow milk with cereal. I breastfeed him at home while he takes ebm at caregiver's place. Could he be allergic to cows milk / lactose intolerant ? Or is it due to ebm ? Will probiotics help ? Tia!
