it sounds exhausting for you

How much sleep is she having in the day? If my dd naps to much she can't stay asleep in the night. At 1, she was having two short sleeps, transitioning to one middle of the day sleep (for about 1.5 hrs) by 14 months.

She could also be going through a massive developmental shift...is she walking yet? Or just about to start walking? Getting new words?

It will pass. I know it seems like it is going to be like this forever, but she will grow out of it.

In the meantime, can you get a break? Maybe family day care for a day or occasional care. Seriously that saved my sanity when dd turned one. It was a little break each week to help me recharge the batteries.
