Is there any way to get baby to sleep in???

S

My little one goes to bed between 6 and 7 depending in when her last nap was. And she will occasionally wake up once at night but sleeps through most nights. She likes to wake up around 4 30 or 5 and wants to eat and is ready for the day. She won't go back down. Which means I have to wait for her to be tierd which is around 2hrs rand put her down for a nap at 630 ish!!! Pushing her bedtime later doesn't help she will actually get up earlier. She is 6 months.
