We are keen to crack on with a sibling for our beautiful DD, who is 4 months old. I am EBF her and committed to doing so until she is 6 months old minimum, but ideally I would carry on until she is a year old. I have 2 frozen embryos and I have discussed breastfeeding whilst undergoing treatment for a FET cycle with my consultant. He is happy to do this, but when I discussed it with the nurses, they seemed much less confident. I would be put on progynova and I gather it can interfere with milk production. Any experience, views or knowledge on this topic? My DH is older and worried about his age and it took us 2 years to conceive DD. It is male factor and the frozen embryos are A+ quality. I would be so grateful for any thoughts.
