Morning routine

Should I be waking my son up in the morning?

Hes 3 months old and we have a bed time routine but not a morning one

He sleeps from 8pm-5/6am (dreemfeeds at 11pm, eats when he wakes up next)

After eating he goes back to bed, and when whenever he wakes up next we start the day (which ranges between 2-5 hours) by feeding, changing diaper, getting dressed.

But should he have a set 7am wake up or 9am wake up? Instead of him just waking up whenever he wants?
