You should be fine. We had one little fellow who went 13 hours, and I never had a problem. If you notice that you are loosing milk supply, you can always add a feeing back in. Until then, enjoy your sleep. I'm a bit jealous. My first two were very good sleepers, but #3 seems to think 4 am is a nice time to wake up. Uugh! Congratulations!
