Baby is in bed with my fiance and I because reasons and my fiance is having the night I had last night. I slept good from midnight to now 4am and when I woke up to feed the baby my fiance says "I haven't been able to sleep. Babies are so fucking scary." Every little noise the baby makes scares him. Which is exactly why he's in bed with us, so I can sleep and not have to sit up every 5 seconds to check on him.
