We use it with no issues. Sam needs a HA formula, but the karicare HA-AR gave him raging diarrhea and incredibly stinky farts - he smelled so bad and pooed so often we couldn't really take him anywhere. Now, with his Nan HA formula and the thickener we have the chucking reduced to manageable levels. We still have the odd bad day/feed, but we don't end up with both of us needing a bath after each and every feed. Sam doesn't poo often, but he's not constipated. We get about every 4 days, but his poos are still soft so it's definitely not constipation.

You've just got to remember that what works for one child may not necessarily work for another.
