Re: Overactive "letdown" even without oversupply?
It's very possible to have fast letdowns and normal supply. It's often not so much about the absolute speed of the letdown as it is about the baby's ability to handle milk flow. A young baby who is still not a super-adept nurser may have difficulty handling even an average milk flow.
That being said, it sounds like you're still experiencing a lot of things that suggest oversupply- like seeing milk spraying or streaming, bloody poops, and very thin-looking pumped milk. You also mention that your feel like you have overactive letdown even when your breast feels soft- which implies that you still feel full or engorged pretty often, correct?
Definitely don't get into pumping and bottle-feeding unless you have no other option- for example, if you have a baby who cannot nurse. I know a lot of women who have exclusively pumped and believe me, it is NOT easier than nursing. The time you're spending right now is nothing compared to the time you'd be spending if you were EP- bottle-washing alone is a huge chunk of your day, and pumping can consume literally HOURS of time. You think it's tough finding time for your 2 year-old right now- imagine finding time for him while not only diapering, cuddling, and feeding your newborn but also spending about 20-30 minutes every 2-3 hours chained to the pump. Nursing freqeuntly is a walk in the part, in comparison!
How has baby's weight gain been so far?
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
