Similac Advance Baby Formula Review

I bought this after my son got bad gas from Enfamil, and he got so consitpated he didnt have a bowel movement for a week in a half we ended up having to give him an enema :(.  after we switched to a different brand of formula I had given the rest of the Similac cans to a friend of mine and the same thing happened to her daughter. I would never use this formula again I dont ever want to put any of my kids through that.

The plus side to this product is they sent you all sorts of coupons and free stuff, but thats the only thing i can think of as positive.
