Thanks, mamas. I'm so pleased with myself for finally figuring out how to do it. It doesn't always work; if one of them is the least bit fussy it all falls apart, and Rachel won't latch any other way besides side-lying during the hours of 7 to 11 at night, so tandem nursing is out then, but even if I only double up a few times a day it still saves tons of time.
I just wanted to brag a little. I had a terrible day and it made me feel better when DH snapped that picture.
