How to get a 1 year old yo sleep in longer?

My little girl doesn't seem to sleep past 5-5:30am 🤦‍♀️ I'm not asking for ages more, just maybe an hour or so lol

She goes to bed at 6:30-7pm, has a bath then bottle just before bed, is put down awake and falls to sleep on her own.

I have tried:

-Earlier bedtime

-Later bedtime

-Bath earlier

-No bath

-No bottle

-Leaving to cry it out in morning

-Going in laying back down, saying goodnight

-Bottle in morning when first wakes

-Water in morning

-Silent toys in morning (in hope she would play a bit and tire again)

-Bringing into our bed

-One nap in day

-Two naps in day

-Naps in morning

-Naps in afternoon

-Earlier dinner

-Late dinner

Nothing seems to work 🤦‍♀️ I'd happily put her to bed late if it meant she slept later lol
