Letter Reversals (b and d): Is It Normal?

Is your child writing b for d, or reading was as saw? Here is when letter reversals are a normal part of learning — and when to take a closer look.

If your child keeps writing b instead of d, or reads 'was' as 'saw', try not to worry. Mixing up mirror-image letters like b and d is a normal part of learning to read and write, and it is very common up to around age seven or eight. Reversals only become a possible concern when they persist well beyond that age alongside other reading and spelling difficulties.

Why b and d get muddled

Letters like b and d, and p and q, are the same shape simply flipped around. In the rest of a child's world, an object stays the same object whether it faces left or right — a cup is a cup from any angle. Reading asks a child to unlearn that instinct: here, direction changes everything. b and d are literally mirror images, so confusing them is a logical mistake, not a worrying one.

This is why reversals are so common in Grade R and Grade 1. The brain is still building the specific skill of noticing and remembering letter direction. Reading words like 'was' as 'saw' comes from the same developing skill of tracking left-to-right consistently. It usually fades naturally as reading and writing become more automatic.

When reversals are completely normal

Occasional b/d confusion, some mirror-writing, and flipped numbers are all a typical part of the Foundation Phase. It is normal to see this through Grade R and Grade 1, and often into Grade 2 as it gradually settles. A child who is otherwise learning sounds, blending words and enjoying stories is very likely just going through the ordinary stage.

The key words are occasional and improving. If your child sometimes flips a b but is clearly getting better over the months, and reading is generally coming along, there is no cause for concern. Reversals alone — with no other difficulties — are rarely a sign of anything more.

Simple ways to help at home

A few gentle tricks help the direction stick. For 'b' and 'd', teach the 'bed' picture: make a bed with two fists, thumbs up — the left hand forms a 'b', the right hand forms a 'd', and the word 'bed' spells out left to right. Many South African teachers use this because it gives the child a reliable check.

Multi-sensory practice works well: let your child trace big letters in sand, salt, or shaving foam while saying the sound, or form letters with playdough. Feeling the shape and direction adds a memory that pen-and-paper alone does not. Keep it playful and brief — a couple of minutes, not a drill — and always pair the letter with its sound rather than only its name.

Avoid making a big deal of each reversal. Calmly point to the correct form and move on. Anxiety around a normal stage can turn a small wobble into a child who dreads writing.

When to take a closer look

Reversals are worth watching more closely when they persist strongly past about age eight, are not improving over time, and appear alongside other difficulties — trouble learning letter sounds, struggling to blend words, unusual spelling, difficulty with rhyme, or reading that stays effortful long after classmates have moved on. It is the cluster of signs, not the reversals by themselves, that matters.

If that fuller picture sounds familiar, it is reasonable to speak to your child's teacher and, if the struggles continue despite good, structured phonics practice, to ask about an assessment by an educational psychologist. In the meantime, steady multi-sensory phonics helps every child — a CAPS-aligned programme such as the SGEG Literacy Learner Path builds letter–sound knowledge in a clear, playful order that naturally strengthens letter direction along the way.

Key takeaways

  • Confusing b and d is a normal, common stage — usually up to about age seven or eight.
  • Reversals happen because b and d are mirror images, and direction is a new idea for young learners.
  • The 'bed' hand trick and multi-sensory tracing help the correct direction stick.
  • Stay calm about mistakes; anxiety can make a normal stage worse.
  • Look closer only if reversals persist past age eight with other reading and spelling difficulties.
