Re: Oversupply, reflux and bobbing
Wow, congratulations on getting your baby to the breast after a rough start! Awesome job, mama!
I think that you are correct that expressing before nursing the baby is counterproductive, because it's just going to perpetuate the oversupply. Don't worry about the hindmilk. There's really no such thing as hindmilk and foremilk- just milk. It's relatively rich in water and carbohydrates and lower in fat at the beginning of a feeding, and gradually becomes increasingly creamy as the breast empties- but even if a baby got nothing but "foremilk" it would be okay, because that lower-fat milk still has everything a baby needs to grow and develop. It's quantity of milk that matters, not quality, when it comes to growth.
Bobbing at the breast- I presume you mean latching and unlatching several times in succession? That's pretty normal towards the end of a feeding. Baby may want a faster flow of milk as the breast empties out, or he may want a slower flow and be frustrated that the breast continues to deliver a rapid flow. Or he could just be tired. Anyway, it's not a big deal and it's something that will disappear as your LO gets older and becomes a better nurser.
ETA: LLLMeg beat ne to it, and she has a brand-new baby! Now I feel like a slouch.
