Baby never wakes up to eat :/

nahw

I am bfing and ever since the beginning my son has never woken up to eat, he's now 15 days old. I nurse him every 3 hours during the day, and every 4 hours at night. I feel like I need to wake him up every 3 hours to keep my breasts from getting too full and engorged. I am also nursing on one breast per feed because I have a great/over supply. Any thoughts on this? I realize he might not be hungry when I wake him up to eat but I feel like I need to in order to help myself as well.

He's awake after feeds or at random times. He doesn't seem to cry for food though.

Crying is a late sign of hunger, are there other cues you may be missing? If baby starts to root then they are hungry.
