Re: Help me with my non-sleeping, cranky daughter!
I just had to find the things of the moment. A thing that worked well was bouncing or rolling back in forth or in circles (gently) on a yoga or exercise ball.
I also found at that age DS wanted to be high up on my back where he could see in a wrap or some sort or a mei tai. Do you have a long piece of sturdy fabric? You can use it to do a high back wrap and see if she might prefer a different position.
I hope you find something that works for you.
