Baby waking too early in the morning

Lynzee

My 7 month old wakes up by 5AM every morning. I’m not sure if this is just her body wake up time or if there is a way to extend it until at least 6 AM. She goes to bed between 7pm-7:30 pm most nights. Therefore she is only getting 10 hours at night and she has always been difficult with naps. She takes three 45 minute naps during the day. We have tried to push her bed time later and she still wakes at or before 5. I am in the process of trying to get her to bed earlier to see if that will make a difference. Any advice or similar situations would be appreciated.
