Final answer:
The ring finger is typically used for a capillary stick for a child older than 12 months.
Step-by-step explanation:
The finger typically used for a capillary stick for a child older than 12 months is the ring finger. This is because the ring finger is slightly less sensitive than the other fingers, making it less painful for the child. Additionally, the ring finger tends to have a good blood flow, making it easier to obtain a blood sample.
