The jury is still out with DHA/ARA additives in formula. Some studies show improved vision and developmental test scores in infants who have DHA/ARA in their diet but then again other studies show no statistical improvements.

As previous people have suggested, I would stick with the lactose-free stuff for at least 2 weeks to see if Sydney's tummy settles. If she's still extremely gassy, another visit to the ped may be in order to address your concerns and discuss another formula change.

FWIW, we use a formula with DHA/ARA with DS just because we started w/ Similac Advanced and didn't want to start formula switching since he seems to be doing fine on it.
