exclusively pumping

Callie • Love my hubs and son(:
So I for the most part exclusively breast feed. I pump every 4 hours sometimes 3, and get between 6-8 oz and just feed my baby the next two feedings from that. So if I pump every 4 hours and get 6-8 oz instead of pumping every 2 when I would get 3-4 will my milk supply be okay? He's 2 months old now
