Perhaps you have realized too, that your child tends to please others even at the expense of postponing his or her own needs and, you are a worried because you have seen other preschoolers “taking advantage” of your child’s kindness.
I call this “Need of Assertiveness”. That is, the ability to stick up for their rights and feelings, with self-confidence.
Assertiveness is a huge asset. If your child wasn’t born with it, you still can help him or she has it. In the classroom, assertiveness puts children at an advantage because it makes them feel comfortable commanding the teacher's attention, raising their hand if they know the answer, and asking for extra help if they are lost. It also helps them have an easier time making friends since they won't hesitate to say: "Hey, can I play too?"
