We just changed to Gerber Good Start Gentle due to sugar in this product.  This did seem to work better than a couple other formula but I decided to try something else when I read about sugar.  We just changed over to Gerber Good Start Gentle and it does (so far) seem to be working better.  He is still gassy but he has less pain and doesnt seem in nearly as much discomfort when eating (he is a little colic but still loves to eat).  I do this this is a good product and I'm sure the sugar is safe, I just would rather not give extra sugar at this age (8 weeks).  Good luck!!

Ex Input:
Switch Orange Tangerine is ok but not what one might expect.  First of all, there is more apple and grape juice in here than orange or tangerine (this will not be a surprise if you are familiar with the other flavors as that is also true with them).  Switch basically is carbonated juice.  The taste isn't a bad and it is supposed to be healthier than soda (which can be debated).  It is a reasonable drink for snacks but if you are going to need several if you are actually thirsty.

I tried this, just one can, and am glad I had not bought more.  I do admire the company for coming up with an alternative to typical soft drinks but it's not for me.  I'd describe it as a sickeningly sweet syrup with very little carbonation added.  Plenty of carbonation is essential to a soft drink, it makes it sparkly and refreshing, plus it counteracts the sweetness.  As I said I'm glad it was just one can, my only regret is that I wasted 1.5 ounces of perfectly good vodka trying to make it more palatable and it didn't.
