TRAVELING WITH CHILDREN-LUGGAGE?
One thing that you can do is to cut your losses before any problems do occur. If your child is going to be carrying luggage, trying to split up the items that are being carried between a carry-on item and a bag that is checked. If you have more than one child, split their belongings between them. In that way, you won’t lose everything if one mistake occurs. If you have anything very important, such as medicine, credit cards or boarding passes, make sure that they are kept on your person at all times.
One other thing that you can do is to label the luggage. There are plenty of sew on or iron on name labels that are available for that purpose, some of which are certain to be appreciated by your child because of their uniqueness. A luggage label does not guarantee that problems are not going to occur but it makes it much more likely that you will end up with the luggage again at some point in the future.
