b and d confusion: why kids mix them up, and how to fix it

Almost every young child mixes up b and d at some point. The two letters are mirror images, and a child’s brain has spent years learning that a cup is still a cup whichever way it faces. Letters are the first things they meet where the direction changes the meaning. With a clear way to start each letter and a little daily practice, most children sort them out.

Why b and d are so easy to confuse

A b turned around is a d. So is a p turned upside down, which is why p and q join the muddle too. When a child copies a letter from memory, they remember its shape but not which way it faces. Under pressure, in a dictation or a test, they write whichever comes out first.

Reading plays a part as well. A child who is still sounding out words reads “bad” as “dad” for the same reason they write it the wrong way: the direction has not yet become automatic.

When it is normal, and when to look closer

Reversals are common while children are learning to read and write, and they usually fade as reading improves. It is worth talking to the class teacher if:

• your child still reverses b and d often after class 2,
• they also reverse numbers, or whole words, often,
• reading is clearly harder for them than for classmates,
• the reversals do not improve after several weeks of steady practice.

If any of these apply, get an opinion from someone who sees many children write.

Tricks that help children tell b from d

The bed trick

Ask your child to make two thumbs-up with their fists facing each other. The left hand makes a b and the right hand makes a d, with the knuckles as the round parts. Together they look like a bed: b at the head, d at the foot. The word “bed” itself starts with b and ends with d, so they can check by spelling it.

Start each letter in the same place

A b starts with a tall line, then the ball: line first, ball second. A d starts with the round part, like a c, then the tall line: c first, then the line. Saying “line, then ball” and “c, then line” while writing gives the hand an order to follow, and the direction comes out right.

One letter at a time

Do not practise b and d on the same day at first. Spend a few days on b alone, with words that only contain b. Then a few days on d alone. Mix them only once both are steady.

Colour

Write b in one colour and d in another on a small card for the desk. Some children remember a colour faster than a direction.

Practice words

Work through these in order, from single letters to mixed words:

1. b alone: bat, ball, bus, bib, cab, tub
2. d alone: dog, dot, red, mud, sad, add
3. Both, the far ends of the word: bad, bed, bid, bud
4. Both, mixed: dab, dub, bald, bend, bird, band
5. Short sentences: “Dad had a bad bed.” “Bob dug a big pond.”

Five minutes a day is enough. Check each word together and praise the ones that face the right way.

What does not help

• Telling the child off for a reversal. It makes them anxious, and anxious children reverse more.
• Long pages of copying. After a few lines the hand goes on autopilot and the mistakes repeat.
• Correcting every letter in their homework at once. Pick b and d, and leave the rest for another week.

Does the handwriting style matter?

It can. In joined styles, b and d start with different strokes and connect to the next letter in different ways, which makes them harder to flip. Our guide to print vs cursive handwriting covers when a child is ready for joined writing.

In our classes, every letter is taught with the LV Method as a short, fixed sequence of strokes, so a child always knows the next stroke. A good grip helps too: see how to hold a pencil correctly.

If you want us to look at your child’s reversals, send a photo of one page through the free handwriting check.

Frequently asked questions

Is it normal for a child to confuse b and d?

Yes. It is one of the most common mistakes while children learn to read and write, and it usually fades with practice.

At what age should b and d confusion stop?

Most children sort it out by around seven or eight. If reversals are still frequent after class 2, talk to the class teacher.

Is b and d confusion a sign of dyslexia?

On its own, no. Reversals are common in all young children. If they come with clear reading difficulties that do not improve, ask a specialist to assess your child.

What is the bed trick for b and d?

Two thumbs-up with the fists facing each other make a b and a d that look like a bed. The word “bed” starts with b and ends with d.

How do I stop my child writing d instead of b?

Teach the starting stroke: b is “line, then ball”, d is “c, then line”. Practise one letter at a time for a few days before mixing them.
