Team, your milk will not dry up over night. Its more likely that getting stressed over it, is going to cause more issues rather than relieve your worry. Plus if your daughter is fractious already, she'll feed off you being upset.
Lots of people mix feed so don't worry about your daughter not coming back to you. She will. DS does not get confused between bottle and boob despite being mainly bottle fed. I thought he wouldn't continue to switch between the two, as he's lucky to be breast feed once a day atm, but he definitely knows where they are and how to use them still.
I have days where my boobs look and feel like they have filled up ridiculously, and days when they look and feel empty. Strangely, what comes out over the course of a day seems to be incredibly consistent day to day. (Remember I actually have the ability to measure this, as I almost exclusively express).
If you get REALLY desperate you could try taking fenugreek supplements. There is supposed to be some evidence it increases supply for some women, if you take the right amount, but doesn't work for everyone. It could have a placebo effect, even if it didn't work anyway though. However its supposed to take 48hrs to work.
DS is still in size 2 pampers at just shy of 12 weeks. We tried Aldi to begin with, but found it a false economy as DS would scream at the slightest wee wetness day and night and they were constantly leaking. When we switched to pampers, he calmed down and could wee more without it bothering him. We will need to step up to size 3s soon, but he's long and skinny. I found we had to really leave it until almost the upper weight for the size 1s when they started leaking before stepping up to 2s. We tried the 2s earlier, but he was leaking with those too.
Btw, thank you to everyone who said about the pump. Its brilliant.
And thank you banana... posts like that are wonderful. Made my day. Whilst feeding has been a battle, I think I've had it easier in other respects, so sticking with it has been easier than it could have been in other circumstances. I'm getting good amounts of sleep which makes a huge difference.
