Surely it should be getting better?! 
Dd age 2.3 has been in her "big girl bed" for just over a month now and we have to do anywhere between half an hour and 3 hours rapid return every single night. It's as if she is tired and ready for bed at 7-7.30, but as soon as we've bathed her and put her into bed she gets a rush of energy and spends hours leaping out of bed, playing with toys and generally not sleeping 
Anyone had anything similar? Is it just a case of waiting it out?
Our friend advised to put a stair gate on her door and just leave her but I hate the thought of leaving her crying at stair gate each night.
Thanks
