What is the best time for corrective surgery for an infant with six toes on the left foot?

  Patient: The child was born one month ago and has six toes on her left foot, both big and small toes are obvious, only there are four more in the middle, all about the same size.  The treatment time for toe deformities takes into account the impact on appearance (psychological problems are also caused by the appearance of the deformity) and the impact of the deformity on the function of the foot (wearing shoes, standing, walking, etc.). It is roughly estimated that surgery should be considered before the child learns to stand, or rather, before wearing shoes.
