I don't know what to do, she's always been a fairly good sleeper but often wakes once in the night but goes back down after a cuddle or bottle. Tonight she's been awake nearly 3 hours. The first 2 hours was spent trying to get her back down. I'm now sat downstairs so my partner can sleep since he has work tomorrow, watching YouTube sensory videos. I know that I shouldn't do it, I don't want to set a standard but I don't know what else to do. She's wide awake. To make things worse she's on 1 nap a day and her wake window is 5 hours so I think I'm going to be up for another few hours yet.
