How to get my baby to sleep in longer?

How do I get my 6 1/2 month old to sleep in longer? She always wakes up around 5-6am sometimes even 4:30am but I will run in to put soother & that usually does the trick

I wouldn’t mind 6am but 5am is soooo early! She used to sleep much longer until like 7am.

Her bedtime is 7:30-8:00pm

Help!
