DD goes to bed early! 6pm and I think thats bc she takes short naps throughout the day. She's then up at 4 am every morning!

I want her to go to bed later so I can spend more time with her when I get home from work and sleep at least until 5!

So, how do I do this? Do I start keeping her up later by 15 min or a half hour for a few nights and then keep increasing?

Ideally I would like her to go to bed btwn 7-8 pm
