What is the reason for my son's soft legs due to rickets?

Patient's question:

My son had a hospital check-up two months ago for rickets, and the symptoms were leg weakness. Whenever he fell, he took calcium supplements, and his legs became strong, and he stopped falling. Half a month ago, he wore a thick cotton pants I made, and suddenly noticed his left leg below the knee bent inward severely, with joint popping sounds. His right leg is normal, and the bending is severe when walking. What kind of help is needed: What is going on, feeling upset

Doctor's answer:

If the child is only two years old now, then this may still be a manifestation of insufficient calcium ion digestion. As a result, the joint development may not be very good, and the legs will certainly not be straight when walking. However, you don't need to worry, because the child is still in the developmental stage. As long as they digest sufficient nutrients, it is definitely possible to recover to normal.
The suggestion is that your child's current condition should pay attention to eating more meat, being more active, taking calcium supplements, and getting more sun. This will ensure that his leg development is normal.
