my baby get is vaccination done on Wednesday after that she is drinking less milk.what was the reason

A. Initially when you get a vaccination done sometimes kids can have this kind of a discomfort due to fever and all and that’s why the feeding can go down a little bit that is commonly seen with kids as a child will start feeling better the pain over the period will see the child will start taking the feeding properly still even after 3 to 5 days if you feel the problem is still persisting the feeding is low and all then kindly check with your doctor regarding that
