TL;DR

  • ·Negativity bias — the well-documented tendency for bad events to be encoded more intensely than equivalent good ones — means empty plates are remembered far more vividly than full ones, making the parent's mental model systematically worse than the actual intake record
  • ·Picky eating affects 27% of three-year-olds and follows a transient arc that resolves in most children by age six; the parent who feels "my child just doesn't eat" is, statistically, in the large majority
  • ·One week of written or photographed meals typically reveals that carbohydrates and protein appear almost daily; having that record at a clinical consultation changes a compressed memory into solid material the clinician can actually use

Lead

You clear the dinner table and look at the plate: vegetables barely touched, again. The question moves through you before you can stop it — is my child actually getting enough nutrition?

The strange thing is that earlier in the same week, there was a day when they asked for a second helping of rice with fermented soybeans, and another when they came home from nursery school having finished every drop of soup. Those days exist, somewhere. But the memory of the untouched plate is the one that stays sharp.

This asymmetry is not a reflection of your attentiveness as a parent. It is the way human memory works. This article looks at that mechanism and argues for a specific and modest response: writing down what your child actually eats, because the act of recording is structurally better suited to calming food-related anxiety than trying to fix the eating.

The memori app keeps the accumulation of feeds and meals in a form you can read back later.

  • Nursing, pumping and bottles run on a timer, with side and volume recorded alongside.
  • Solids build up into a list of what's been eaten, so a first-time food is easy to spot.
  • Height, weight and head circumference are drawn over national reference curves.
