Ok question all you lovely mama's - I have been nursing my 2 week old on the regular and have not been pumping at all. He's been eating fine and often. However, I have noticed pain in my breasts if he takes a longer break between feedings or right when he starts to eat. It doesn't last long, but it feels like a brief tightening pain that fades away. Is this an indicator that I should be pumping a little to ease some discomfort? Thanks for any feedback!
