This floating thumb baby is very cute, he was crying all the time when he came for review, but he was very cooperative. After the second stage surgery, functional exercise is the most important thing. If the functional exercise is done well, the baby can do many things, so whether the mom or dad takes it by themselves, or grandparents or grandparents take it, they must help and guide the baby to do functional exercise. Unlike older children, younger babies are more emotional when it comes to functional exercises, sometimes they are very cooperative and sometimes they are more rowdy. Parents should be patient and first make their babies aware that their thumbs can be used, and then encourage them to use their thumbs more often, for example, by giving them some toys they like to play with and things they like to eat.
