Are flashcards good for toddlers?

17 October 2026 · Soundly

Short answer: flashcards will not teach a baby to read, and that has been tested properly. But pictures absolutely do teach toddlers words — under two conditions that most flashcard packs get wrong.

The claim that got tested

“Your Baby Can Read” was the biggest product in this category — DVDs, flashcards and word books, sold on the promise in the name.

In 2014, Susan Neuman and colleagues published a randomised trial of it in the Journal of Educational Psychology. They followed 117 infants for seven months, one group using the programme, one carrying on as normal, and measured both early precursor skills and actual reading using eye-tracking and standardised tests.1

Across 14 assessments — letter names, letter sounds, vocabulary — the two groups differed on none of the 13 that covered those skills. The babies did not learn to read, although many of the parents were confident that they had.

That last clause is the uncomfortable part. Parental confidence was high and measured ability was unchanged. In 2012 the US Federal Trade Commission took action over the advertising, and the company agreed to stop using the name “Your Baby Can Read” at all.2

Worth being precise: this tested one commercial programme built around drilling. It is strong evidence against the reading claim. It is not evidence that showing a child pictures is useless — and the research below says the opposite.

What pictures genuinely do

Children learn real things from flat pictures, and younger than most people expect. Patricia Ganea and colleagues taught toddlers a made-up word — a “blicket” — for an object they had only ever seen in a picture book, then put two real objects in front of them. The children picked out the right one.3 The word crossed from the page to the world.

So the picture is not the problem. What matters is which picture.

Condition one: make it look like the real thing

Transfer from a picture to reality gets stronger the more the picture resembles what it depicts, and weaker as the depiction drifts from its real-world referent.4 A cartoon pig with a round pink face and a smile is a long way from a pig.

This is the part flashcard packs most often get wrong, because illustration is cheaper than photography and more appealing to the adult holding the card. The child is doing a harder job than it looks: deciding that this flat coloured shape stands for a thing in the world.

Condition two: one picture is not enough

Here is the finding that should change how you use a card deck.

Perry and colleagues taught 18-month-olds names for new categories across nine weekly visits. One group saw three very similar examples of each thing. The other saw three quite different ones. The high-variability group learned more of the trained categories — and then generalised better to entirely new words they had not been taught.5

The mechanism is intuitive once stated. Shown one dog repeatedly, a child can attach “dog” to that particular shape. Shown a greyhound, a sheepdog and a puppy, the child has to work out what they share, and that is the word. Related work points the same way: 30-month-olds retained new words only after meeting several exemplars of a category,6 and toddlers taught six examples of a colour word generalised it better than those taught four or two.7

Being straight about the limits: this effect is well replicated when an adult is deliberately teaching a label, but studies of “cross-situational” learning — where children infer words from ambiguous scenes — have found variability made little difference.8 The research is strong for the way you would actually use cards with a child, and weaker as a universal law.

So: are they good for your toddler?

They are fine, and they are not magic. What the evidence supports is narrower and more useful than either the marketing or the backlash:

The honest summary is that the cards were never the active ingredient. A realistic picture, a few different ones per word, and an adult saying the word out loud — that is what the research supports, whether it arrives as cardboard or anything else.

Where Soundly fits

We built Soundly around exactly these two conditions, which is why it looks the way it does: every picture is a real photograph, never an illustration, and there are five different photographs and five different recordings behind each of its 72 subjects, shown in turn rather than at random, so a child meets all five before any repeats.

Each one also plays the real recorded sound, and an English voice actor naming it. You can hear a real cow, pig or horse here without installing anything.
