LO not eating today- part of growth spurt?

beckysuejune07

LO has been going through the 6 week growth spurt all week- some days eating non stop, others sleeping non stop and only waking to eat, but eating on a normal schedule. Today he has been sleeping non stop and wakes up to eat but only latches on for 3-5 minutes before unlatching and falling back asleep. I have tried burping him, changing him, wiggling around etc to wake him to no avail. His last decent size feeding was at 11:00 today! Is this part of the growth spurt?

 I am pumping right now because  he has ibcreased my supply so much this week I was leaking and engorged from barely feeding all afternoon.
