Anyone else's LO have odd sleep habits/patterns

JennMM

DD has developed a very predictable sleeping schedule and she does STTN so this is not a complaint at all. She goes to bed around 9:30 right after her last bottle (sometimes a little earlier or later depending on how fast she eats). She usually fusses for a few minutes and then goes to sleep. She will sleep for about an hour until close to 10:30-10:45 at which points she begins to cry and fuss periodically for anywhere from 30 mins to an hour. The funny thing is, she isn't really awake. I can go upstair and check on her and she is obviously asleep. The fussiness is not continuous and very half hearted so we just let her be and she gets quiet again. After this, she sleeps quietly for the rest of the night. My DS went through a phase where he would wake up every single night at exactly the same time and cry for 5 minutes and then go back to sleep. It's funny how they have their little eccentricities with their sleeping patterns.
