Hindi ko na-try personally yung Infini Pro HW kaya hindi ako confident mag-compare, pero from what a few of us moms talk about sa group, pareho silang premium NAN formulas designed for sensitive tummies, the main thing is baka different ang exact nutrients or maybe one's for a specific age range, so best talaga to check the labels or ask your pedia since they know your baby's needs best! Sorry hindi ako makatulong ng mas specific, pero if you find out the difference, sana i-share mo din sa amin hehe!
