hii doctor, my son is 5yr5m old, he didn't have my feed since day1 as I couldn't produce milk, and due to lact of knowledge I started giving him cow milk very early because of that he frequently affected with cold cough and allergies and he has heat body also just like me, and unfortunately because of my financial issues I didn't provide him all vaccines only he had government provided vaccines, so now I can afford for some extent so how do I take care of him so that I can avoid medicine and antibiotics all the time and what vaccines can he have now to avoid future health issues. please suggest me
