Re: Need help please!
Since your baby is still very young, is sleepy, and is generally having such small, green poops, I think I'd take the precaution of taking her back to the pediatrician and have her re-weighed fairly soon. Maybe in a couple days, perhaps as long as a week? And meanwhile, I would watch diaper output really carefully, keep a careful log, and do everything you can to make sure that your baby stays alert and active at the breast, takes both breasts, and nurses at least 10-12 times a day.
The PP's advice on bottles and pumping is good. You don't want to get into all that unless it's necessary. It just makes more work for you, messes with your baby's latch (potentially), gets you into a mindset where you're always measuring your pump output and your baby's bottle intake against each other... (And babies almost always take more from the bottle than they do from the breast, due to the mechanics of bottle feeding.)
The pediatrician's advice on the time your baby "should" be spending at the breast is silly. Feeding speed varies widely, even with newborns. Some can get all they need in just 5-10 minutes, others require closer to an hour. Your baby may be able to get her needs met in just 10-15 minutes.
One thing that can really help with sleepy babies is something called switch nursing. When baby starts to fall asleep at the breast, transitioning from active nursing to shallow, fluttery "comfort" suckling, you remove her from the breast, change her diaper or burp her, and switch her to the other side. You repeat the process as many times as necessary, until the baby will no longer wake. You probably want to combine this with breast compressions, to speed milk flow to the baby.
Useful link on diaper output: http://kellymom.com/bf/got-milk/supp...s/enough-milk/ Note the part about the stools- kellymom says you're looking for at least 3-4 per day, around the size of a US quarter (2.5 cm) or larger. Based on that, your LO's output seems a little low.
