I would try Nutramigen. You could try the Gentle Ease, but Nutramigen worked wonders for my son at 8 weeks. And switching formulas isn't good on their systems either. If you do switch formulas, mix them. Then it isn't so shocking to their system. What i mean, is I mixed 4 cups at a time and when weening my son from nutramigen to enfamil, mixed 1 scoop of enfamil and 15 nutramigen. If switching to see if one helps w colic better, you could do it 1/4 or 1/2 and work your way up to the new forlmula. But constant switching doesn't help the problem either. Hope that all made sense!
