This was a weird drink - I had high expectations, but the flavor was just odd - it really did taste like fizzy Tang drink mix.  However, my kids really liked it, and I think it is a great alternative to junky soda, so I will most likely buy more - but not for ME to drink.  ;)

If your child is truly lactose intolerant, this product is great.  If fussiness/gas is an issue, then consider staying with Similac Advance or another formula that is made primarily with **milk**.  This product did seem to create less fussiness in our baby, but honestly I think the Dr Brown bottles made a bigger impact.  Make your own trade-off between fussiness vs. nutrition, just be aware of which formulas are made with corn sweeteners and which are truly milk-based.  It's misleading for the company to label the product as "milk-based" when it has minor ingredients "derived from" milk.  Read the list of ingredients (below).  I found the ingredients on the parent company's website (Abbott Nutrition).  Don't try to find the ingredients list on the Simlac website -- it's not there (perhaps for good reason).  SIMILAC SENSITIVE Ingredients: Corn Maltodextrin, Sugar (Sucrose), Milk Protein Isolate, High Oleic Safflower Oil, Soy Oil, Coconut Oil, Galactooligosaccharides*. Less than 1.0% of the Following: C.
