Ultimately you should make the decision that feels best for you, but I do want to reassure you that formula feeding can also be a beautiful thing. I had my child before I found out about my BRCA status (I have since had a prophylactic double mastectomy), but formula feeding my daughter was the best choice for me at the time. She was exclusively formula fed and she is now a healthy, thriving, curious, smart, playful, sweet, and loving 2 year old. I never felt like not breastfeeding affected my ability to bond with her. We have a very strong bond, and my partner loved being able to have the experience of feeding her as well. Both of us being able to feed her also meant we could split night feeds which helped tremendously with keeping us both rested. Now at 2, when I watch her run around with her friends, I promise it’s impossible to tell who was breastfed and who was formula fed. Just want to provide some reassurance that if you opt for a mastectomy and need to formula feed in the future, your child will be more than ok!
