you probably do produce enough milk, but if you're worried about it, be sure to drink plenty of water. It probably has nothing to do with her being hungry. My son uses me as a pacifier. He eats ALL the time and wants to stay latched on even when he's falling asleep. Most likely, because your daughter is sucking so much, you'll realize in a couple weeks that you have more milk than she could ever need and she'll probably just starts spitting up more after each meal since, if she keeps sucking that way, she'll get more milk than her stomach can hold.

If you don't want to use anything else, there is really no advice I can give. Just let her keep going. She's still pretty young. Eventually, she'll be able to go without being latched on and start sleeping on her own. At two weeks, though, it's very common for babies to just want to be on their mother's chest all the time. Remember, she used to be inside you. She knows your heartbeat better than you do!

Thank you for your advice. My eldest daughter didn't want to breast feed, so this is all new to me.
