When Should Children Start Learning Letter Sounds?

How to introduce letter sounds through playful, low-pressure experiences while following a young child’s interest and development.

Short answer

There is no single birthday when formal phonics must begin. Young children can meet letter sounds through songs, books, conversation, and play whenever they show interest. Keep it brief and enjoyable; systematic reading instruction becomes more important as they approach school-age reading.

Children can become curious about print long before formal reading instruction. If a toddler points to a letter, enjoys an alphabet book, or wants to hear a sound again, it is fine to respond. The aim at this age is a warm introduction—not a deadline or a race through 26 letters.

Follow interest, but make the connection clear

Name the letter, say a common sound, and connect it to something meaningful: “That is M. It can represent /m/, like the first sound in Mama.” Songs, signs, names, books, and playful apps can all provide brief encounters.

A parent’s experience

“My son began choosing and squishing Phonics Bugs at about 18 months. By 22 months, he could identify the letter sounds across the alphabet.” This is one family’s experience—not a timetable or a promised result for every child.

Readiness looks like engagement

A young child who returns willingly, listens, points, or experiments is participating. They do not need to perform on request. If they turn away or become frustrated, pause and return another day. Shared reading, conversation, songs, and free play remain essential foundations.

What should instruction look like later?

As children begin learning to read, playful exposure alone is not a complete plan. They benefit from systematic teaching that connects phonemes to graphemes and shows how to blend them. See how to choose a first set of sounds and how names and sounds work together.
