I have both oversupply and an overactive letdown. In the beginning I would offer both breasts to DD and realized she was only getting foremilk because she had green poop. So then I read about oversupply and realized that was then problem so then started doing only one side at a feed. At that point she was eating very frequently, maybe every 1-2 hours. Which I am now finding out is too much as I was misreading her cues. I am currently trying out the E.A.S.Y schedule which has her eating every 2.5-3 hours (usually closer to 3 but that's her choice as she only eats when she is hungry).
She sleeps, and whenever she wakes up (when she is hungry I assume) is when she eats, we play, once I think she is tired I start putting her down and the cycle repeats. I am still doing only one side per feed. However, she only wants to eat at the longest 10 minutes, milk is always dribbling out of her mouth and all over me, she sputters, chokes, etc. But because of how her feeds are spaced out now I am going at the shortest 6 hours of not feeding one side and the longest was a bit over 8 hours.
I am concerned because she has started having liquid green poop which she never had before. I assumed that waiting that long between feedings on one side would help lower my supply. So why did she start with liquid green poop? And what can I do? I don't want to pump between feeds because it will make my oversupply worse.
