My twins love a 1am stand up and chat to one another every now and then, one of them enjoys a couple of laps around the cot and 100 miles an hour. On the odd occasion they’re up for 30 minutes. To start with I went in the room to encourage them to resettle but it made it worse as I think they just thought I was joining the party. I just ignore them now and they soon settle themselves back down again.
Yes she's sitting up in sleep lately.....
They do this alot when learning a new skill. When in our LG learned to crawl she used to randomly sit up in the middle of the night and try and crawl round the bed (which was alot of fun at 2am as we could slept every night 🙈) it was exhausting but it does pass. It's total normal behaviour xx
