Overfeeding?

My LO is 2 months old and i'm currently feeding him Naan Optipro 120ml every 3 hours. Im not sure if i'm over feeding him as we have been increasing his milk intake but we did not extend the interval to feed him. Realised that the recommended feeding table behind the formula tin is 150ml and 5 times daily only. Please advise. Current: 120ml x 7 times = 840 Ideal: 150ml x 5 times = 750
