Yes we'd all prefer that 7am wake up.
This is such a difficult question
If she wakes up happy then she is ready to start the day, so you kind of need to feed her
But if she wakes up grumpy then maybe she jsut can't get the last sleep cycle going so maybe try PU/PD to get her back to sleep
Getting that magic 7am start up can sometimes mean playing around with the day routine... a later (or earlier bedtime) later or shorter naps... it can be a bit of trial & error, but some babies (like my first just are early risers & nothing will change that... I've been trying for over 2 years)
