How to deal with the separation anxiety
When children are unwilling to be separated from their parents, one of the wrong approaches is sneaking away. It makes children feel even more afraid that parents will suddenly leave, and destroy the trust between children and parents. It will be harder for them to settle when you leave them next time. Conversely, it is not advisable to prolong the goodbye process. Try not to return to them when they start crying, or go back and forth which makes your children more difficult to separate with you.
When you are leaving your children, the right thing to do is to tell your child you’re leaving and tell them you will be back at a certain time. Be specific and define the time that they can understand, e.g. after nap time or play time. It takes time for children to understand your words and your promise "mommy will be back at 12nn" or "parents must come back to see me.’’ When this process repeats consistently, it allows your children to build trust between you and them.
Some children may take a longer time to get adapted to the school environment. During this period of time, parents should remain patient and gentle. Smile to them when saying goodbye. Keep a relaxed and happy look on your face. If you look angry, worried or sad, it will only make them feel more complicated.
