Successful breastfeeding for 2nd baby?

Were any of you unsuccessful with breastfeeding for your first baby but ended up being able to breastfeed your second?

I tried so hard to breastfeed to my baby but it just didn’t work out, he was losing dramatic weight and was almost hospitalized and I had to supplement with formula then I switched to all formula. Anyways, I’m going back and fourth if I want to even try breastfeeding my second since I had such a bad experience but then again I’d like to try... just nervous I won’t have a good supply again. Also I worry about feeling guilty that I couldn’t do it with my first.

Idk I’m rambling lol I 100% agree fed is best, it’s just a personal feeling
