Feedings

Crystal
I am currently breastfeeding and my daughter is 12 days old. My doctor told me to wake her every 3 hours for feeding. Do you all wake your babies up for feedings or do you wait for them to get you up for their feedings?
The reason why I ask is because my friends are telling me to never wake a sleeping baby. I have a doctors appointment on Monday so I'll ask him again then. 🙂
