Gripe water?

KM
Every afternoon after nap time, and every night around 3am, my LO is super uncomfortable kicking his legs out and passing tons of gas!!  It's not the true definition of colic, but he's uncomfortable and gassy. I've tried tummy massage, moving his legs, and a probiotic but it's still happening. It doesn't seem related to my diet. I'm considering trying gripe water. Anyone have any experience or recommendations?
