9 day old… weird eating today

Baby boy has been eating on one side for about 10-12 minutes. Then sleeping. Then waking up shortly after and then eating on the other for a short amount of time then repeat.

He is eating every hour at this point.

Usually he stays on for 20 minutes each side.

Not sure what’s going on but is this normal?

My engorgement is gone away. & he is still having the right amount of diapers.
