If big people do it, children will want to do it. They imitate and try to be just like you. They are always watching and wanting attention. If you give your attention to medicines and cleaning products, so will they. Cleaning products are a part of everyday life.
Adults choose when, how much, and what cleaning product is needed.
Young children cannot make such choices. Medicines are a part of everyday life. Adults choose if and when medication is needed. Young children cannot make such choices. Children need to know they come first.
