Drink lots of fluids, but stay away from caffeine if you can. At home, pump after each nursing to get any last drops out.
Do nurse on demand at home. I found my son wanted to nurse a lot through the evenings, and usually 1 or 2 times at night. Nurse both sides if at all possible. If he's not nursing both sides at a feeding, pump on one side while he's nursing on the opposite side. Let him nurse as much and as often as possible.
For me, the biggest thing was sleep---I slept pretty much any chance I got, every chance I got, and DH was great with trying to help me. Our house was an absolute wreck until about DS was about 7 months, when he started nursing a bit less and so I could do afford a little less sleep. But I'm one of those that needs 8 hours of sleep, and with work and nursing, it just drained me.... So I napped during every nap time that the baby took.
When you pump, having a picture of the baby in front of you, or his clothes from yesterday (with his smell on them), or having a recording of your baby laughing or babbling can really help trigger you to relax. I also had a sort of mantra that I repeated (in a monotone) "I make plenty of milk for my baby" while I was pumping. I also read a book while pumping, so I was immersed in something that I found interesting and didn't think about it (for some women, thinking about it can kind of block you from relaxing.... for me, because I've been around animals of various kinds my whole life and have seen other animal momma's nurse, I made it a sort of joke, and called myself "the cow;" I was just doing what ).
On the weekend, starting on Friday night, try not giving any formula at all the whole weekend--he'll nurse like crazy but it will stimulate you to make more milk (its not fun, I know! but it's natures way of cueing our bodies to make more). And my milk supply was definitely lower, pumping, at the end of the week than at the beginning.
You might want to fit in 2 pumpings in the morning, instead of 1. Studies have shown that nursing women make most of the volume of their milk in the morning before noon, so if you can push one of the sessions back to 11:45 or something that might help.
I've heard that you can supplement w/ fenugreek, but I didn't try that.
There were definitely periods where I felt that there was nothing there in body.... (I can remember crying about it because I was so tired and thought I was "failing" my baby). But we just kept at it.
And if you try all this and it still isn't working (I'd give it a couple of weeks), don't beat yourself up about it. Any breastmilk is good for them, and if you need to switch to formula, that's okay, too. As long as momma is happy and healthy, that is what is best for baby.
