He's what....2 weeks old? The first 6-8 weeks of establishing milk supply is just one giant growth spurt. They feed often to make sure that your body produces the milk it needs for his emerging needs and anything that interferes with that will make a supply issue, or a perceived supply issue, worse. As others have said pumping output is not
an indication of how much milk you do or don't have. There are other ways to determine that. Have a look at Kellymom
for more info..there's heaps of it there and it was my bible.
:info on what to expect in the early weeks, including common concerns.
He sounds to me like he's just being a normal 2 week old baby and offering formula won't resolve supply issues, if there are any, it will just make it worse. If you are having latching issues I really do encourage you to get some professional bf advice if you want to continue to bf. A Lactation Consultant would be my first port of call, then maybe the ABA. You are just learning how to be together, and he's had a shock by going from the nice warm, safe environment of the womb where he was rocked to sleep and fed whenever he wanted so give it some time. Google the 4th trimester, it's pretty interesting stuff.
Good luck, you're doing a great job and hang in there....ooh and congratulations. <span class="emoticon smile">smile</span>
