Sleeping through the night

I'm generally a pretty good sleeper, but I like to wake up around 4 to 5 am (after 8-10 hours of sleep) to nurse before returning to sleep. Then one morning instead of getting my Mommy with her nice soft bosom, my Daddy came in with a plastic sippy cup of milk. I've decided it's not worth waking up for that, so now, I've been sleeping from 7 to 7 - 12 hours solid at night!
