Engorgement in the middle of the night?

Christa.

So I normally wake up in the middle of the night to pump but I never feel engorged. I actually never really pump that much either. Well around 11pm I pumped after feeding my daughter but she didn’t finish eating. She wouldn’t take my second breast which is totally fine. I pumped off about 2 ounces but I thought it was probably due to her not finishing. Then I just woke up with her now and she’s nursing which she doesn’t normally do in the middle of the night but she’s been sleeping with one arm unswaddled to work on self soothing when she wakes up. She will generally wake up, talk a little, use her hand to soothe, and fall back asleep - not needing me but I know that takes a lot of energy so I’m not surprised she’s a little hungry and otherwise she’s been doing her pattern all night. My question is does my body just know she would need to eat tonight? Or is it from something I ate. The one new thing I did during the day is drink 2 cans of pineapple juice because I read on here that recommendation for increasing supply. Boobs are amazing either way, they felt fuller and somehow knew my baby needed to eat tonight.
