Formula feeding on demand or schedule?

Ma

I breastfed my baby the first two weeks and she is now a little over two weeks and eating formula. The day she turned two weeks old she started not wanting to wake up during the day to eat. She does fine with waking up on a schedule at night but during the day she is so hard to wake up and would probably go all day without eating if I didn’t wake her up. When she was breastfeeding, the pediatrician said to feed her on a schedule. What I’m wondering is, now that she is formula feeding and over 2 weeks old, should I still be waking her to eat?
