Hi mommy! Based sa Lactum 1-3 packaging, it's usually 1 scoop (which is the scoop inside the tin) to 2oz of water, yes! Best to double-check the instructions sa back ng can mo though kasi minsan may slight differences depending sa batch, pero yan ang standard na ratio na sinusunod ng karamihan sa amin, one of my mum friends and I always do that and it's consistent. If unsure ka talaga, pwede mo ring i-call their customer service or check the exact instructions on your tin to be sure!
