I've not taken Bromazepam, but hopefully others who have taken it or something similar can join in and share their experience. I would say to ask your doctor again if it's ok to take while breastfeeding. It can't hurt to ask and you will rest easy knowing you are doing the right thing.
See, the way I see it is that you must take care of yourself first so that you can be 100% available for other people like your baby.
I breastfed two of my babies and the third one I couldn't because I was on several drugs like Seroquel and others that I just can't remember the names to. I don't want to tell you that you can't breastfeed and I realize how important it is for you, but talk to your husband or someone close to you and get support and I just want you and your baby to be ok. Bonding was something I still did by carrying my child all the time, even in a sling when she was a little older. They just love being with momma.

My bottle fed baby and I bonded very well and to be honest I was so sick emotionally that I welcomed the help that feeding with a bottle came with, like others helping to feed her and I could get some rest.
This is a quiet forum but if you have anymore questions I'd be happy to chat with you. Hugs! I do understand that feeling of wanting to breastfeed and bond with your baby.
