Clinging unlike hugging is an urgent demand for immediate attention. Many young children have difficulty separating from their parents. I have enrolled my son in the kindergarten, but he refuses to leave me and won’t go in the door unless I stay there with him the whole time. So this kind of problem is often faced by many parents. The image of preschooler clutching his mother’s shirt ,hanging for dear life while she tries to cook or work out the door is not make –believe for many parents . It’s a real and emotionally draining part of everyday life. It may be tough to resist the temptation to constantly attend to them .But sometimes you have to tell him in a sincere voice that you are proud of him or  happy that you have a chance to play with so many friends of his age when going for the first time to school. Most children overcome their fears of separation by age five. Some times, a child had an unpleasant experience; it is not unusual for the child to cling when facing that kind of situation. To prevent this problem, there are some suggestions for you:
Practice leaving your child with relatives or friends:
You’ll have to put the idea in the mind of your child that you may not always be around , practice leaving him occasionally for short period of time or for few hours early in his life . These breaks are good for both parents and children.
Tell your child the details of your absence:
When parents are going out, it becomes a duty of every parent to tell their child where you are going and make him know who will look after him in your absence. Describe what he’ll be doing and where you’ll be while you are away, so he won’t worry about his fate or yours.
Play a game hide and seek:

In the early stages of any child’s life, this simple game gives him the enormous joy. This simple game gets your child used to the idea that things go away for a time being but more importantly, come back. Toddlers and preschoolers play this game in variety of ways like by hiding behind their hands or some object. Through this example this clinging problem can be solved to some extent.
Make sure your child that you’ll be coming back:
Don’t forget to tell your child that you’ll be returning and also prove to him as good as your word by coming back when you said you would.
Preplanning of separation with your child helps:
Tell your child that you’ll be leaving and plan the suggestion in advance that he can cope while you’re gone. If you surprise him by leaving without warning, he may always wonder when you’re going to disappear suddenly again.
Praise your child for handling separation:
Make your child proud of his ability to play by himself. This will further reinforce his self confidence and independence, which will benefit both of you.
You’ll be a good role model for feeling okay about being separated and having good time with other people. Provide lots of hugs and kisses during neutral times, to prevent him from feeling ignored. However, when clinging becomes routine for a child, the behavior needs attention. It is difficult for a parent to let go of a screaming child. Sometimes we feel as if we are abandoning our child in a movement of need. Try to let go of those feelings. Your child needs to learn to be more independent, and you role as per parent is to help your child.
