Breast feeding Tips? 🤱🏼💖

I’m not sure if this is allowed in this group... I’m a FTM of 8 month old twins. My fiancé and I have started to plan when we would possibly want to try for a 3rd. I so badly wanted to EBF my twins but I was so exhausted trying to feed them every two hours separately, that I didn’t sleep hardly at all for the first 2 weeks. I was lucky if I got an hour and a half of sleep a night. So I turned to formula for both of them after about a month while still pumping for the next 6 months following. My supply plummeted and I had tried everything in the book to get it back up. I want to do all I can for the next baby so that I can successfully breast feed exclusively. What worked for you, what would you suggest, any tips or tricks? I just want to be prepared for when the time comes and be more educated this time around on it. 😋
