我有个任务就是给国内亲戚代购婴儿奶粉，一直都从Costco买Similac牌的。大概是前年或去年Costco突然决定把Similac Advance奶粉换成Similac Advance Non-GMO。 最开始是两种摆在一起卖，但价钱一样。等到普通版的卖完以后店家就把Non-GMO版的价钱涨了上去了，大概每份涨2-3刀的样子。我们没有选择，只好冤枉地为这帮疑神疑鬼的反转活动分子买单。
Similac还在继续生产普通版的奶粉，只是Costco选择不卖它。今天上亚马逊看了一下，发现有不少人抱怨他们的baby在吃了Non-GMO版奶粉后出现喷射式呕吐（有18%的顾客给了一颗星的差评，多数因为他们的baby受不了这个版本的奶粉）：

Sad this doesn't work for my babies.

I was so excited that Similac came out with a non-GMO alternative. Iinstantly bought up many containers (I have twins). Unfortunately, my babies for some reason cannot tolerate the non-GMO product. This has me very sad and very puzzled... as they projectile vomit after every non-GMO bottle, but tolerate the 'regular' formula. Just a personal experience.

My experience may be different but I am also reading other parents that went through this. This caused my daughter extreme projectile vomiting for the past 2 days and I'm still trying to wean her back to the original similac. Her doc said she's been seeing GI upset with this formula and when she called similac they stayed there was no difference. I have read what they use to replace the gmo is what makes babies sensitive to it. I wanted parents to know my experience and maybe save someone's kid from going through this

Be warned...

My one month old had horrible diarrhea and terrible gas pains from this. We used the regular similac advance and had no issues, the non GMO is what's doing it! Be warned... This stuff is brutal on your little ones belly.
