I attend the breastfeeding support grouop that is held on tuesdays from 1-3 at the Scarborough Maine Med. Learning Center, it is free. That answer has come up and my daughter who is 15 weeks old sleeps about 9-11 hours per night and I do not wake to pump. Karen the lactation consultant that runs the group said you shouldn't because if you do you will always have to. Your body will go through an adjustment period of a few days where you may get engorged it may be a little painful, but after a few nights you should be back to normal. Your milk supply will not go down, and you could probably use the sleep. It is a supply and demand, so what your baby needs, your body will supply, right now you are making more milk than your baby needs if you are pumping. I am also a stay at home mom and I do not pump, thank goodness, because I hate pumping. If you have more questions you can always call Maine Med. and ask the lactation consultants there, they are very helpful. I used them a lot at the beginning as it took me 6 weeks to successfully breastfeed. Good luck.
