My Son Is Two Months And 5days Old..I Am Very

My son is two months and 5days old..I am very much worried when my baby cry when he felt there is trouble in his stomach. I breastfeed him for two months but i suddenly stop due to my stomach pain .I'm afraid my baby can feed also my pain..I already went to the pedia and she gave restime for my baby but the pain still there..
Please answer my questions that really bother me..
1. Is it possible that whatever the pain I felt inside my body , my baby can also feed on it?
2. Do I really need to stop breastfeeding my baby?
3. What will be the best infant formula for mybaby?
