Wow and yay for twins!!!!!!
My experience bf'ing my twins wasn't stellar but I had absolutely no clue what I was doing and we had a horrible birth experience among other things so we made it to six weeks.
HOWEVER.......I learned this: your body will meet demand especially if you get things started ebf. Please contact a twin or multiples group in your area. Any support you can get irl with twins is going to really help you. Your milk tends to come in faster the second time around and that should both help you and boost your confidence in the early days. I went on to ebf my singleton with tons to spare most times. I had a ton of help due to my anxiety over making enough milk. Plus some other minor issues
I have a friend irl who ebf'd her twin girls to 14 months. It can be done.
I will throw it out there that I thought I would save time by trying to feed them together but it was far easier to get one done and then the other as they took only 20 mins to feed. I think if I did one at a time from the start I would have had more success with it. But again, get a location consultant on your side. it's not too early to start speaking with one.
Congrats again
Twins are a lot of fun
