Anyone experience with relactation?

I've been reading quite a bit about the process of relactation. *No judgement please.* I stopped breastfeeding my son around a month and was exclusively pumping. I did that until he was about 6 weeks. I didn't have much support and was feeling overwhelmed as a ftm. My son is almost 5 months but I've felt in my heart since then I shouldn't have given up. I'm seeing that it's very possible but want some advice or tips.
