Sleep regression?????

[pinkpixiepanda]

My LG has not long since turned 2.
Since 10 weeks old she's been a great sleepers slept through the night and gone to bed no problems.
Lately she will not go to bed! She is happy going to bed and having her story but once I leave she screams and paddies and cry's and runs out her room.
If she doesn't do it when she's going to bed she's walking up during the night doing it and asking for mummy's bed!
Tried everything I can think of and I just don't know what's wrong or what I can do to break this cycle!
Any advice/ suggestions will be welcome

I'm not sure if it's a sleep regression at this age. There are some pretty big back teeth that come in before 2 and a half, could it be those that are troubling her?
