when should i wake baby to feed?

our daughter is 8 days old and we had our appointment with our pediatrician at 4 days old. pediatrician recommended waking the baby to (breast) feed during the day every 2-3 hours and feed on demand after 12am so she learns the difference between night and day. i feel like waking her every 2-3 hours during the day is getting used to eating that often? last night she woke every hour 1/2-2 hours 😩 what do you do for your newborn feedings?
