Calculation notes

This is a practical planning estimate only, not feeding or medical advice.
For newborns, premature babies, feeding difficulties, illness, weight concerns, or dehydration worries, speak to a midwife, GP, health visitor, or NHS 111.
Follow your formula tin, healthcare advice, and your baby's cues.

Feed planning

How the daily feed estimate is shaped

The feeding type matters, so expressed milk, breastfeeding and formula scenarios are kept distinct.

Feeding assumptions

The calculator uses the baby's age, weight and feeding type to produce an estimated feeding pattern or bottle volume range where appropriate.

Feeding type is kept explicit so expressed milk, breastfeeding and formula scenarios are not mixed together.

Feed-estimate pathage, weight and feeding type -> estimated daily pattern or bottle-volume guidance

Bottle-planning scenario

Example: bottle-planning scenario

Age: entered by parent
Weight: entered by parent
Feeding type: expressed milk or formula

Result: The output gives a practical daily estimate and splits it into feeds across the day where the selected scenario supports that.

This is a planning estimate for bottles and routines, not a rule for how much a baby must drink.

Planning, not prescribing

Babies vary a lot by growth stage, illness, cluster feeding and routine, so observed feeding cues matter.
Use NHS guidance, a midwife or health visitor for feeding concerns.
