You may be talking about OTA's nevus. If it is indeed Ota's nevus, it is treated with laser now, and the effect is not bad. Now the latest technology is the new emerald laser treatment. It is very simple to distinguish between a new laser and an old laser. But the new laser will not make the skin bleed during the treatment, and the old Nd:yag laser will make the skin bleed during the treatment, but the most important thing for such a small child is the pain during the treatment. In fact, you just need to go to the hospital and find a doctor to try it with a laser. Moreover, for such a small child, local anesthesia is not local anesthesia, and the pain is similar, which has no effect. Even if you are numb for a long time, you still have to rely on adults to grasp hard. For such a young child, local anesthesia has little effect. If it is useful, there is no need for adults to master it. Such a young child needs general anesthesia, but general anesthesia is risky, so most hospitals do not do general anesthesia. Therefore, unless you pay special attention, doing it for such a young child is a valuable thing and painful. Many hospitals can say nothing, nothing, can do it, can do it, but if it hurts, you will know how painful it is for children. If you try it yourself, it is enough to experience it. You can judge for yourself whether to make it for such a young child, or apply anesthetic and try again, and you will know that it is almost the same. You can refer to my article, and your illness has been understood.
