A practical example
Among the principles of upbringing, one important one is that the person who is instructing the children should himself/herself present a practical example of whatever he/she is teaching the children.
Small children have a great tendency to imitate whatever they see. When children see someone do something, they try to imitate it. Thus, when children are asked to offer Salaat, this method is not as effective as oneself offering Salaat and asking them to join in. Whatever we want to teach children, if we start doing it ourselves, then children will also do the same.
