Digging around with a needle is perhaps the most common way of removing a splinter, but this needle can introduce infectious agents. For children in particular, a needle can also be scary and painful, as can repeatedly squeezing the skin around the splinter, whether that be in the fingers, the hand, the feet, or in some other area of the body.
However, and especially if it is a wood splinter, you may be able to apply a poultice or liquid that will help the body to soon expel the sliver relatively painlessly.
Natural Cures: Earth Clinic users have found that using vinegar or a white bread poultice can help you remove a splinter easily and help to prevent infection of the surrounding skin. Tape may also be applied to pull out the exposed end of a sliver, or a paste of baking soda applied to the wound may cause the sliver to expand so that the splinter pushes itself back out of the hole in the skin.
