Little Sydney slept from 10:45p to 5:45a last night. We don't know who makes the call on the true definition of "through the night" but we're claiming victory.
At her age, that is definitely "sleeping through the night". Congrats! Victory is yours! (Did you guys freak out and check if she was breathing like we did?)
I know the feeling. It's funny how we used to be so tired because we only got 5 or 6 hours of sleep, "pre-baby". Then when you have a newborn, you feel like you can conquer the world when you sleep for 5 or 6 hours straight.
