Planning with formula

Why amounts vary

How much babies drink changes from feed to feed and day to day. Use a recent typical day as your starting point.

Tins and scoops

Each brand has its own scoop size and ratio. Enter the grams of powder per 30 ml from your tin for a closer tin estimate.

Keep a spare

Many parents keep one extra tin at home so they’re never caught short.

FAQ

Questions parents ask

Does this tell me how much my baby should drink?

No. It only multiplies the amounts you enter. For feeding guidance, talk with your healthcare professional.

How is a month calculated?

We use 30 days.

What if I don’t know the powder ratio?

We use 4.5 g per 30 ml as a rough placeholder. Check your tin for the exact figure.
