Thanks, ladies. I was pretty sure it wasn't worth the trouble; in 5 weeks, school is out for the summer and I get to be a SAHM for 2 months, during which time I'll probably do all the night feedings, and DS will probably start sleeping through the night and this problem will be eliminated. DH seems to think that my boobs are like a faucet and I can just pump out 6 oz whenever I feel like it. Guess he needs to realize they're more like small kegs that need some time to refill, lol.
I'll try pumping in the morning on my days off and then pump right before bed and right when I get up to try and keep up a sort of nighttime supply.
I appreciate your suggestions!
