Feeding on both sides??

that’s her 🤪✨ • •mother of three 💙 •Nurse Kim👩🏾‍⚕️• hoping for my baby girl🤞🏾🩷✨

How long should a four day old be nursing on each side?? The pediatrician says both sides in one feeding but my little one will feed for 15 to 20 minutes on one side each feeding. What have you all been doing?
