Hi Straffles,
Didn't want to read and run but just wanted to send you big hugs xxx I have a little one same age, who's also going through the 2-1 stage. About a month ago we had a night from hell, she probably had about 5 hours sleep in the night and we had about 1! I was a zombie going to work the next day...and of course I asked myself how does my daughter get out of her OT.
I know that babies are different... but I learnt after that night that babies really are very resilient. She was full of beans the following day and we just went with the flow and read signs as best we could. She never did catch up on all the sleep she lost, but I realised that after a couple of days, that she didn't need to. I wondered if she would do it the following night but thankfully she didn't. But others are like this night after night... and they manage.
Lots of deep breaths, you will get through this, just like you have all along....xxx
Oh, and I still don't know why she was like that through the night.
