I am dealing with the same thing, only my daughter is now standing up in her crib all of the time (also ten months old). I am battling her for naps during the day and she has been waking up in the middle of the night, which is quite odd.
My daughter is able to lay herself back down, but she just doesn't want to! She will be half asleep when I lay her down and she immediately rolls over, sits up and then stands up at the crib. The only thing I have been able to do is just leave her standing there...She'll start crying and I let her for a little while and usually she wears herself out. Then, I go back in and lay her down, rub her back a little bit and she goes to sleep.
Honestly, I think we're getting to the stage where sleep will be a little off. I think I will have to readjust to her sleeping patterns. Good luck! Let me know if you come up with anything :)
