Every other night, LO's sleep is awful and the other nights, it's great. We don't do anything differently so I don't know why this is happening.

Thursday night she slept 8 hours then 2 more. Last night she slept 3 then 3, then woke up at 3:30, 4:30, 5:30, and finally 7. We start her bedtime routine at the same time or earlier if she's tired and it's the same routine every night. We have the heat set on the same temperature but it might vary a bit depending on the temperature outside?

It's pretty consistently every other night though. Has anyone else had this happen?
