What have I done 🥲

So while my little dude was in the nicu. I supplied him via pumping and (thank god) built up a freezer stash as I was over producing. When he came home, we originally were told to fortify. We did. And I was still making enough to stash and feed. Then I decided ya know what let’s try putting him directly to breast again without people hovering and my anxiety of hospitals. He took to it like he’d been doing it forever. Awesome. Well I didn’t want to loose bottle feeding though for help. Well now he’s 4 months and I’m pretty sure I’ve lost my supply. I used to be able to produce 4-5oz every pump every 2-3hrs. I only BF at night, he usually only wakes up once around 3am. Feeds for 15 and falls back asleep. (I used to wake up leaking at times, that just boom stopped.) We get up around 7:30-8, and I pump. Feed him that via bottle. I eat oatmeal for breakfast to help supply. Have been since day 1. But suddenly I haven’t been feeling full again really… ever tbh. I’ve started having to use my stash because when I go to pump again 2-3hrs later, I get less than 2ozs. I mean I slacked on my pumping schedule here and there, bf him here and there during the day too. Did my body get used to his night snacking and thinks that’s all he needs or something?!
