I'm thankful these times are rare

The little guy didn't get to sleep until midnight last night and woke up around 2:30, 4:30 and then again at 6. I can usually nurse him back to sleep quickly, but he thrashed around the whole time which is quite uncomfortable for me. I gave up and got up to put him in his swing in hopes that it will lull him back to sleep. He's yawning lots and also making grunting noises, but no sleep. Maybe he has gas? Sleep, baby! Mommy needs more sleep, too!
