How did you know if weight loss or exercise were impacting your supply?
I have lost about 5 lbs in one week, I think because I cut out dairy (tying to see if it resolves some mild symptoms in my 4 month old)

A few times in the past two days she has been more fussy at the breast and in general. Of course she has also just hit the 4 m. Sleep regression, and is teething, so there is a ton of stuff going on for her.

I don't pump, so I'm wondering how I would even know if supply had dropped without a weight check (and I'd like to know before her 6 m appt, obviously.
