6 week growth spurt

Tara
Talk to me about the 6 week growth spurt. My LO has been sleeping nonstop and doesn't usually nap that well during the day. Should I be waking him up to eat (during the daytime hours)? He usually eats every 1.5-3 hours during the day and my boobs are starting to leak everywhere since he's so sleepy. Wake him? Or pump? This is all new to me since during his 3 week growth spurt he ate nonstop for 72 hours and barely slept.
