I'm going crazy! LO is 6.5 weeks old and FF, and usually eats 22-25oz a day.

He has never eaten more than 4oz at a time since before yesterday and suddenly he is unconsolably hungry!! So so fussy, won't sleep or nap hardly at all, and the only thing that calms him is more food! He has already eaten 26oz today, and easily has 2-3 more feedings.

Is this what a growth spurt looks like?!! Do I keep feeding him or try to cut him off (which results in screaming and misery)

Help!
