T.C.
Ohhhhhhhhhhh I know what you are going through. When my daughter was the same age we went through the same thing. She learned a new skill and wanted to use it all the time. The DR told me this is a constant on her mind and that she would do this until she had it mastered. She would run around for hours in her crib... I would hear her walk from side to side and occasionally fall! Finally about 3 weeks or so later she had it mastered and we got her back on a normal sleep schedule after a few days. She would also cry in frustration as she was tired but wanted to keep working at it.
As for what to do... I have no idea, I just waited it out like the DR suggested and lost plenty of sleep sure that she would slam her head on the crib and be unconscious and I would not know it... more grey hairs added to my head!
I wish you luck and hope you get some rest soon... take naps if you are able to, it helps!
Many blessings to you and yours!
