A few days ago, a two-year-old baby with polydactyly came from the provinces, and asked the mom why she didn’t have the surgery earlier. The mom said that her family thought that polydactyly was not a big problem, and that they would talk about it after the baby grew up. However, the mom thinks that the baby will be going to kindergarten soon, and she is afraid that the baby will be teased in kindergarten, so she wants to have the surgery. For babies with polydactyly, I usually recommend surgery before they can walk. Because babies are very smart, if the surgery is done after the baby can walk, after the surgery, the baby will feel that his/her foot has been injured and will have all kinds of protective movements, and all kinds of gait will come out at this time, so it is a better time to do the surgery before the baby learns how to walk. In addition, the earlier the surgery, the less the baby’s psychology will be affected. In outpatient clinics, children who have already started kindergarten often come to see the doctor, and many of them have mentioned a problem, that is, in kindergarten, they will be asked by classmates what is wrong with their hands or feet. Therefore, parents must pay attention to their children’s psychological problems, and if surgery is possible at the right time, parents should let their children undergo surgery as early as possible. If there are other problems that prevent surgery, parents should provide guidance so that the child’s mental health is not affected.
