I think it was one week?This was 3 oz in how many days? Sorry, I can't figure it out from your posts
Were you able to add additional nursing sessions as we suggested? Still supplementing 2 ounces total per day during that time?
but two ounces is a normal sized feeding for a baby this age. A baby this age needs about 25 ounces of breastmilk a day, some a little more. They usually get this by nursing at least 10 times a day. It varies, in part because normal milk production varies.When I pump at my fullest I get 2 oz total at most which I believe tells me that I'm not making enough
So a normal sized feeding is about 2 ounces, sometimes more, sometimes less. Plus you are still nursing at least 8 times a day-yes? And pumps are often not as good as baby at extracting milk. So how much do you expect to be able to pump?
I think it is time to go back to your IBCLC or consider seeing another one. Breastfeeding needs to be seriously re-assessed so you can get clarity on what is happening so the underlying issue can be addressed. I am disturbed that everyone including your IBCLC is throwing formula at the problem as if that will solve the underlying issue. But it will not. Maybe you do have low production, and that can be addressed various ways. But from what you said about your IBCLC appt, there also may be an issue with your baby's ability to transfer milk. And sometimes. slow weight gain has nothing to do with what or how much baby is fed.
You may need to supplement, it happens. Much better from a health standpoint to give baby needed supplements along with breastfeeding than to not breastfeed at all. But it should be a supplement. Not almost an entire feeding. You DO make milk. Enough to keep your baby alive and to grow, although slowly. So that is very close to 'enough.'
This is kind of urgent because you are on your way to no more breastfeeding, which I assume you do not want. If baby is supplemented 1.5 to 2 ounces every time you feed your baby, that is what-10 - 16 ounces per day? That is a lot, almost half to over a half of what your baby needs total. Your baby is getting close to being entirely formula fed, almost certainly unnecessarily.
When your baby fusses after getting the bottle, have you tried offering the breast again? Anyone suggest the 'finish at the breast' method of supplementing to you?
