Waking up earlier.

My 5 month old will sleep between 8-11 hours a night. She has 3 naps in the day and 4 10oz feeds. She use to have a bedtime between 10pm/11pm, I’ve started changing her bedtime to 8/9am-8am but she sometimes she will wake at 5 or 6. Do I give her an extra feed in the day and an extra nap? Or do I just give her an earlier bedtime? (I do wake her up from her naps, normally two 1 and a hour hours and a short nap in the evening between 25-45 minutes)
