Rickets Symptoms in Children: Bowed Legs and Late Walking
Bowed legs, swollen wrists or a child who tires on walks can signal rickets, a bone problem linked to low vitamin D and calcium. This guide sets out the rickets symptoms children can show, how a doctor confirms it, and what parents can safely check at home.
Age bands used here are under 6 months, 6 to 12 months, 1 to 3 years, 3 to 6 years, and over 6 years. Where the advice on food changes with age, the text says so, and the doctor judges a child against the band the child is in, not against a single rule.
At a glance
- Main sign: bowed legs, according to the NHS.
- Main cause: low vitamin D and calcium, according to the NHS.
- Who confirms it: a GP, who may use blood tests and a urine sample, and may refer to a specialist for X-rays or bone scans.
- Never at home: setting a child’s vitamin D amount. The pack, a pharmacist or a doctor sets it.
- The line to remember: one photo proves little, while a series of photos over months shows what the doctor needs to see.

What are the rickets symptoms in children?
The NHS names bowed legs as the main sign. Other symptoms include swollen, painful wrists, and pain in the back, shoulders, ribs, pelvis or legs. A child may change the way they walk, not want to walk much, or tire quickly when walking. Weak muscles can make stairs or getting out of a chair hard, and muscles can tingle, cramp or twitch.
Children can also break bones more often, or after a minor accident, especially at the hips, lower back and feet. Affected children may be shorter than their peers, and their teeth may come through later than usual. That list is longer than bowed legs alone.
A soft skull, which many parents search for, is not on the NHS list. A home check cannot settle it, so raise it with the GP or health visitor. If bowing or bone pain is present too, do not hold the question back until the next routine visit.
Why does vitamin D matter for a child’s bones?
The NHS says vitamin D helps regulate calcium and phosphate in the body, and that these nutrients are needed to keep bones, teeth and muscles healthy. The body makes vitamin D when skin is in sunlight. Between October and early March, the NHS says, the body does not make enough vitamin D from sunlight, so food sources and vitamin D products matter in those months.
Calcium comes from foods such as milk, cheese, yoghurt and green leafy vegetables. The NHS says rickets and osteomalacia are usually caused by low levels of vitamin D and calcium. Sun exposure in the Pakistan context is covered in the vitamin D and sun exposure post, so this piece does not repeat it.
When is bowed legs a reason to see a GP?
The NHS rickets page says to see a GP if you think a child might have rickets. That advice is non-urgent, but it is not a reason to wait for months. The page does not give an age after which bowing needs checking, so ask the GP or health visitor directly at the next appointment.
In the meantime, a simple record helps the doctor see the direction of travel. Use these steps.
- Take one standing photo a month. Photograph from the front and the side, in the same spot on a flat floor and in similar light.
- Write the age in months. Put the age on the file name or in a note, so the photos line up with the child’s growth.
- Note any pain or limp. Record pain in the bones, changes in walking, tiredness on walks, and any bone that breaks after a small knock.
- Keep the record for 3 months. A few months of photos and notes shows the direction more clearly than one picture does.
- Bring it to the GP. Ask whether a blood test is needed, and ask the age from which the doctor expects bowing to settle.
The photo log that shows change
Keep one folder for each child. Use the same spot, the same light and the same position every month, so the pictures can be compared side by side. Add a short note on pain or walking alongside each date.
How does a doctor confirm rickets?
The NHS says a GP checks vitamin D and calcium levels, which may include blood tests and a urine sample. The GP may refer the child to a specialist for tests such as X-rays or bone scans. Do not start a vitamin D product on a guess. The amount for a child is set from the pack, or by a pharmacist or doctor, and the doctor decides whether a test or a change is needed.
Do food and sunlight decide it?
They matter, but not on their own. Sunlight on skin makes vitamin D, and the NHS notes that the body does not make enough vitamin D from sunlight between October and early March. Calcium from milk, cheese, yoghurt and leafy greens also matters. From 1 year, a glass of milk or a katori of dahi is a food amount that supports the diet, not a treatment for rickets. Under 1 year, milk for a baby is breast milk or formula, and cow’s milk is not a main drink.
Book a GP visit if a child has bone pain that does not settle, weakness on the stairs, a limp, or a bone that breaks after a minor knock. Bowing that gets worse, or that is still there when the GP expects it to have settled, needs a check. Breathing fast, breathing with effort, chest sucking in, blue lips, or a child who is drowsy or floppy needs urgent care now. Never set a child’s vitamin D amount at home.

Questions parents ask about rickets in children
What are the rickets symptoms in children?
The main sign is bowed legs, according to the NHS. Others include swollen, painful wrists, bone pain in the back, shoulders, ribs, pelvis or legs, changes in walking, weak muscles, and bones that break after minor knocks.
Is rickets caused by low vitamin D or calcium?
Both matter. The NHS says rickets and osteomalacia are usually caused by low levels of vitamin D and calcium in the body.
Are bowed legs in toddlers always rickets?
No. Bowed legs are the main sign of rickets, but a sign is not a diagnosis. A GP checks vitamin D and calcium levels, which may include blood tests and a urine sample, before anything is confirmed.
Baby not walking by age, is vitamin D the reason?
It can be a reason to check, but not a reason to start a home product. The NHS lists changes in walking, not wanting to walk much, and tiring quickly when walking as symptoms of rickets, so a GP should look at the child.
Is a soft skull in a baby rickets?
A soft skull is not on the NHS rickets symptom list, so it cannot be confirmed at home. Mention it to the GP or health visitor at the next visit, along with any bowing or pain.
Can sunlight prevent rickets in kids?
Sunlight helps the skin make vitamin D, but it is not a guarantee. The NHS says the body does not make enough vitamin D from sunlight between October and early March, so a child can still need checking.
How is rickets diagnosed in a child?
A GP checks vitamin D and calcium levels, which may include blood tests and a urine sample, and may refer the child to a specialist for tests such as X-rays or bone scans.
Can you give a child vitamin D without a doctor?
Do not set the amount at home. The pack, a pharmacist or a doctor works out the amount for a child, and a doctor decides whether a test or a change is needed.
Does food alone prevent rickets?
Food helps, but it does not do the job alone. The NHS says calcium is found in foods such as milk, cheese, yoghurt and green leafy vegetables, while sunlight on the skin makes vitamin D, so diet and sun both play a part.
When should a child with bowed legs see a doctor?
See a GP if you think your child might have rickets, which the NHS describes as non-urgent advice. Bone pain, a limp, a child who tires on walks, or bones that break after minor knocks should be seen soon rather than left for a routine check.
