Problem: Article: Cut the ankle out of the sock. Cut a small triangle off at the ankle, leaving it attached on the top side.  If the sock is long enough, you can cut off the foot all together. Basically, you want to create on log tube that will fit over your arm. By cutting off just the heel, you create a tube that lays flat on your arm. Use a sock that you don't care about, as you will be damaging it beyond repair. Snip off the end of the sock at the toes so you have an even toe. Leaving about two inches or so at the bottom of the tube, cut out a small section to fit your thumb through. Using sharp scissors, cut a half circle in the folded sock, creating a hole for your thumb. Pull the sock up as far as you want the cast to come up your arm. If it's too long, cut off part of the sock to make it shorter. However, you want to leave some to fold over the end of the gauze. Starting at the bottom, wrap you arm in the gauze. Leave some space at the bottom of the sock to fold over the gauze. Overlap each layer. When you reach your hand, wrap over and under your thumb, leaving your fingers free. Don't wrap it too tightly, as it will cut off circulation. Fold the ends of the sock over the gauze. This step isn't vital, but it will make the ends look neater. Starting at the folded over edge of the sock at the bottom, wrap colored tape around your arm, overlapping as you go. You can use masking tape or duct tape.  Make sure not to wrap it too tightly. You don't want to cut off the circulation. Work in smaller pieces to make it easier. Use about a foot of duct tape at a time so it doesn't fold back on itself. You can use sports pre-wrap in place of the tape. If the edge of the duct tape overlaps near your thumb too much, carefully cut off the edges.
Summary: Use a white sock. Cut the toes off the sock. Cut a hole for the thumb. Put the sock on your arm. Wrap your arm with self-adhesive gauze. Fold the sock back over the gauze. Use colored tape to wrap your arm. Cut off an excess tape at the thumb.

Problem: Article: Provide plenty of praise for trying this new thing, even when they're not sick. Try getting a fun box of tissues with interesting patterns or designs on it to encourage your child to use them more often.  Try different varieties of tissue paper, and have your child tell you which one they prefer. Some children may be extremely sensitive to texture or scents that you may not even notice. Having a tissue paper that the child doesn't mind will help this teaching process tremendously. Make sure you have plenty of the kind of tissue paper your child prefers ready when they're sick. When your child is sick, it's likely that he'll resist doing anything new. They will likely want to be left alone, or cuddled, so be gentle. When you have a cold, you can use this opportunity to model using a tissue to blow your own nose, encouraging your child to imitate.  Siblings can also serve as role models for your child as they learns how to blow their nose. Younger siblings might be distinguished by the fact that they aren't old enough to blow their own nose. Often, this comparison has a good deal of attraction for an older sibling. Explicitly point out the steps of blowing the nose, as you do them or as others do. Narrate the process as you go through the steps. They might need to be reminded to close their mouth.  Keep a gentle, light tone of voice when teaching this new skill. If your child wants to hold the tissue themselves, let them! While it may be easier for the child to learn simply by blowing into a tissue you hold, some children may prefer to be in charge of their own tissue. Consider using a humidifier or saline spray to help loosen the mucus if your child is struggling to blow their nose while sick. This may mean that you go through more tissues than you'd like, but teaching the routine of throwing the tissue away will benefit you, and your child, in the long run.  Sometimes the routine of throwing the tissue into the trash can will be a fun incentive for the child in itself. Provide plenty of praise for each tissue that goes from tissue box, to nose, to trash. Always have a trash bin close by as you are teaching this process. If you don't actually have a trash bin so close at hand, improvise by finding another receptacle (such as a plastic container, or an empty bowl) that can function as a temporary trash location until you can move it.
Summary:
Practice holding a tissue to your child's nose. Point out when yourself or other adults use a tissue to blow their noses. Help your child blow their nose when they're sick by holding the tissue to their nose and telling them to blow. Teach your child to throw away the tissue immediately after they finish blowing.
