This Similac Alimentum formula works great if your child is or might be lactose intolerance as my son.  His tummy wouldn't tolerate any of the normal formulas that they went through at the hospital until they decided to try the Alimentum as one of the last resorts.  I have never had any issues with him vomiting or loose stools and he received the nutrition he needed while still keeping it down.  He seemed to really like it and it was a smooth transition to soy milk since the consistency is about the same.

The only two drawback that this is by far one of the most expensive formulas out there. ...
