My ds 12mths does that ... but we are lucky enough that a quick cuddle from both me and dh is enough and ds can go back to his cot and fall asleep... we tell him that it is night time and time to sleep not play...kiss him goodnight and leave the room 9/10 times it works! Ds goes to daycare and when he comes home he is so tired he just crashes in cot with a bottle and doesnt move til 1030 /11pm and either has a bottle and goes back to sleep or the above happens. Hoever if he wakes at 2-3-4am i just leave him talking away and eventually he falls back to sleep.... (obviously if he is getting upset and the talking changes to 'i want you mum NOW' cry obviously i go check him .....
I would suggest if you can leave her in her cot and if she has a tanty well she has a tanty hey she will learn (i dare say the hard way) that night time is for sleep not playing with mum and dad eyelids lol....
Is she cold ? That could be another reason she wakes up .... We have a oil heater thing in the room and it is beauitiful .... not to warm but not too cool either.

Cheers
