Wind can cause tummy aches.

Our little lump has a definite pattern in the evenings (ie, 8pm-11pm) where he goes into major snack mode. Left boob, right, left, right, then rejects the boobs and turns into a googly-eyed bundle of wriggles (I usually hand him to my partner for this since he isn't the boobie bar) and then he goes down for 4-6 hours at around 10:30-11pm. That sleep got shorter in his last growth spurt but I'm hoping it starts to get longer again, him going down for 8 hours would be absolute bliss *sigh*
