Total newbie question. My milk came in last night and today I started feeling full and borderline engorged (but not engorged yet). After I nurse LO and he detaches when he's done it's definitely better, but it still feels pretty heavy and full compared to before my milk came in.

Is there still milk left? Or is this just how they normally feel? Should I pump it if there's extra and store it? I know I'm giving LO what he needs but I'm paranoid about low supply as we establish breastfeeding.

I'm lost. Haha. Any advice or guidance?
