Ah, there's something to be said about the stress that comes from watching the freezer supply dwindle down to nothing. I BF both of my children for about a year each. I pumped at work and froze the milk. They were each exclusively BF, so that frozen supply was SO important for daycare. Before you pay $75 for a LC, you might first check out some FREE resources like La Leche League. Or try some of the suggestions from other moms.
I always nursed my baby on one side per feeding. My right side always produced probably twice as much as my left. I still alternated between sides after each feeding, to make sure to keep up the supply in both sides.
I would suggest that you try to pump on one side while you nurse on the other. Mornings were the best time for me to do this...I could get a lot of extra milk, because I was more full from the night. If your left side is usually fuller, feed baby on the RIGHT side for the first feeding of the day (this side will be fuller than usual due to going through the night), and pump on the left side at the same time. It's a little awkward at first to do both at the same time, but it can be done, and I think you'll find that you get a lot more milk, because your baby is already stimulating the let-down.
I have a hospital grade electric double pump that I have used with both babies, but there are still times when I had a tough time *tricking* my body to release that milk. Many women have said to get a hand pump and take it into the shower with you. The warm water will help with the let down. You might try this if you are extra full.
