Emptying my boobs

My little boy doesn't have a good latch and has just last week been diagnosed with a posterior tongue tie - might be worth u trying to get LO assessed for one too. (My LO is 10 weeks and it's only just been found)
I have to now feed and do a breast compression (press hard on top of my boob) to help him get milk out and I delatch him when j can't hear and see swallowing...if u check online I'm sure there will be a video to show you the difference (effective feeding sucks are much stronger and not fluttery) we have been advised to top up after every feed as well but he is definitly getting more from me directly now. Hope this helps x

Breasts don't ever empty fully, think of them as a river not a lake so they're constantly flowing and refilling it's an endless supply.
We don't know how much baby has had off the breast which I find hard myself at times but Ive always been told that as long as nappies are wet and dirty often there's no need to worry. Breast milk is also different to formula as it changes to suit babys needs so only an Oz of breast milk could be the equivalent of 4oz formula.
If you've been pumping everyday it could be that pump parts need to be changed now too as they need replacing every so often. Are you doing it consistently at set times as that also effects pump supply?

As long as nappy output is good I'd keep working on latch if that's what you want to do and try not to worry about amount although I know myself it's easier said than done! X
