It is also possible for a 2-year-old baby to develop nephrogenic oedema, as common diseases such as nephrotic syndrome and acute glomerulonephritis occur in children, so it is important to pay attention when a 2-year-old baby develops unexplained oedema, especially sunken oedema in the eyelid area or in areas of loose tissue such as the lower limbs. Prompt medical attention is recommended to screen for the presence of kidney disease.
