You can start using a positive approach to discipline for children aged 3 years and older. At this age, children can understand how to behave in positive ways – for example, being cooperative, thinking of others and sticking to family rules. But they’ll probably need help to understand, remember and practise this kind of behaviour. This is where discipline comes in.For example, you might have a family rule about behaving gently towards each other. A positive approach to discipline might involve using a consequence like time-out if your child is hitting their sibling.Our preschooler behaviour strategies have more ideas for guiding your child’s behaviour in positive ways.
