Removing a splinter can be painful and difficult enough for an adult, much more so for a child. If a piece of the splinter is protruding from the skin, you can easily take this out using a pair of tweezers.
If there is only a very small part that is protruding, you can get a piece of Band-Aid or any other adhesive tape. Place this gently but firmly over the splinter and peel it off. The splinter should stick to the tape.
If there is nothing sticking out, you will have to use a sterilized needle and ‘perform surgery.’ First soak the part with the splinter in warm water – this will soften the skin. Use the sterilized needle to cut the skin above the splinter, then pull it out with the tweezers.
