Is any of this happening?
Be seen today
Seek prompt medical advice if a child cannot bear weight, has sudden severe bone pain, develops a new limb deformity, or may have a fracture.
These can be signs of dangerously low calcium or another urgent condition.

Does any of this apply?
Book an appointment
Arrange a routine medical appointment if a child has persistent bowed legs, widened wrists or ankles, bone pain, delayed walking, muscle weakness, slow growth, or risk factors for vitamin D deficiency.
These findings do not always mean rickets, but they should be assessed.
Every sign above is quoted from the sofidex article on Vitamin D deficiency rickets. If you are not sure, err upward — it is always reasonable to be checked.
