Is it selfish to try nursing again now?

background: first baby didn't gain enough weight nursing and had a bad latch. we switched to pumping + formula. my supply was never enough for what he needed.

second baby we saw a lactation consultant 3x, her latch was fantastic, but I was anxious about weight gain so was also pumping. supply is much better but had a lot of issues pumping this time and had sores, bleeding and pain for weeks so I stopped trying to nurse. finally it's all cleared up and was considering trying nursing early in the morning when I know I have a decent supply ready. was about to try today but didn't because I felt like I was being selfish. we've been exclusively pace feeding and use Evenflo bottles. last time I tried nursing her 3-4 weeks ago her latch was still great, but she's 19 weeks now. should I give it a try or is that being selfish and I should just keep exclusively pumping + bottle?
