I was born a little less than a month early about 26 years ago. Perfectly healthy thanks to a healthy biological mom. Gained weight quickly after birth, left the hospital in a few days. Had my bio mom been an obeast like my brother's (who was not a premie, but born addicted to narcotics and suffers from her fat shittiness to this day), it would've been a much different outcome for me.  I'm not saying your parents were lazy or fat at all! I had one thing going against me, you probably had one thing going for you (your parents). But had there been more issues than just me being impatient and jumping into (or out of) things too quickly (like I do today pretty much), it wouldn't be the same happy story for me today.  Tl;dr: (cuz I'm tipsy and not making sense right now): shit goes down when you're a baby, you need your parents to be on their game because you're completely reliant on them for everything. It's on them to make sure you're healthy, or get the best chance to be healthy if you're dealt a crummy hand at random.  PS Your parents sound awesome and I know my fiancé and I would do the same thing if it were us facing something like that.  PPS If you've gotten this far, thanks for reading my ramblings. May God grant you a magical unicorn that shits confetti and diamonds.
