Eh, biasa orang start around 6 months when baby dah mula makan solids, tapi honestly best tanya pediatrician dulu sebab setiap baby beda, my friend's kid had goat's milk from 8 months sebab dia ada sensitivity dengan regular formula, but dia kena introduce slow-slow je. I haven't tried Wildan sendiri, but a few of the mummies in my group tried goat milk formula and they say it's gentler on the tummy, just make sure proper formula grade ya, not plain kambing milk sebab bayi kena specific nutrients. Ada any tummy issues with your little one ke, or just exploring options?
