See that the necessary things get done. Another family member may have to take over some of the things you usually do. Children will learn that this is part of what it means to be a family. Get outside help if necessary, especially if you have side effects from repeated treatment that could worry young children. It is also best, if possible, to have the same person helping, especially when there are young children who need consistent care.
Children are often more able to accept body changes than adults.
Give a brief explanation of why you look or feel the way you do, and let it go at that. You may well find yourself a subject of gossip among the local children. On the other hand your children may not want to admit that anything has changed in your home. Let them know you are willing to talk to their friends if they want you to. Try to be relaxed if changes must be made, and involve children as much as you can in the new plans.
