Hi Elliott, maybe you just have a really inefficient let-down with the pumps, like me?
dunno if my two-pennies worth helps, but I panicked initially before I started work cos I was expressing DISMAL amounts with the Avent- about 2 oz in 2 sessions of 30 minutes each... if I was lucky!my s-i-l was expressing like a dairy cow with the pump, her let-down was REALLY efficient..
But I just couldn't go on like that, so in the end, I bit the bullet and forked out for a Medela double pump, and it worked wonders for me, amazingly. I managed to express about 4-5 oz in 15 mins when I started using it!
After 2 weeks of using it, I do find that it gets better with practice. Definitely. so I wouldn't get discouraged..Also so much milk builds up during the day when u start work so it's easier then too... I find that I prolly get more milk out faster with the pump than when I b/f now that I'm working, but then it might just be my imagination!
I usually try to leave pumping until the very last minute, when my boobs are engorged the MOST and I think I can't wait any longer, cos of my inefficient let-down . I find that the more engorged my boobs, the more milk I can express! Now I get at least 6 oz in less than 10 mins..
But the usual advice is that you should pump more regularly to maintain your supply, so maybe I'm not giving good advice..
Plus I don't have a suitable place at the office to pump, so I normally let 6 hours slide without expressing...
Someone gave me some good advice, that it helps to have pictures of your baby, or other babies when expressing, helps let-down (stimulates prolactin or something??)I find that helps..
also you could try expressing just after a hot bath or shower..that gets it flowing too...and massage your boobs while expressing..or get dh to do it..????
it's important to relax too...I know we all get so stressed out when there's just so little trickling out..but if you just relax and forget abt what you're doing, it somehow happens!!
Good luck...
