The third nap is always in my arms too! I've let her miss it before not out of choice and then bed time is a disaster and she doesn't feed well either. That's why I'm rocking her to sleep for it at the moment. If she could extend her other two sleeps, she would be able to get by. I would like her to be able to drop it though.
You're right Rose&Aurelia, once she starts moving about she will get more tired and sleep longer. She is allowed to have her brace off in the day time now, so she has been rolling around everywhere.
She must have read my initial post though, because she has been up so much in the night since I wrote it!!!!
