I second what Artechim said about a later bedtime. I was on my own for a month while DP was away and just got sick of it taking more than an hour to get DD2 to sleep so I just put her to bed at 9pm. My mum said she used to put me to bed at midnight because she got sick of battling me

Also think about getting rid of the daytime nap. I know she's very young still but maybe just try it for a few days and see if that brings her bedtime forward. My DD needs 12 hours solid awake time (I know she's older but at least working out her pattern has made it easier for me to predict what time her bedtime will be)
