Hi Doctor, I hope this email finds you well. I wanted to reach out to discuss some concerns I have regarding my baby's recent transition from formula milk (Nan Pro) to cow milk. Since switching to cow milk, my baby has been experiencing very hard constipation, with bowel movements resembling hard nuts. Additionally, she has been experiencing vomiting episodes, and it often takes her 2-3 days to have a bowel movement. I'm quite worried about these symptoms and would greatly appreciate your guidance on how to address them ok
