Hi! Ah yes, Lactum, maraming moms namin use din yan. Usually ang Lactum for 1-3 years old is 3 heaping teaspoons (or around 25g) per 200ml of water, pero honestly check mo agad ang canister niyo kasi sometimes may slight difference ang measurements depende sa batch. Best to follow kung ano talaga ang nakasulat sa back of the can para sure ka, at kung gusto mo ng exact measurement, you can also call their hotline, super helpful sila about feeding quantities!
