Parents today face endless advice, much of it confusing or contradictory. Ideas come and go, from claims about classical music improving brain power to new methods for helping a baby sleep. Yet one piece of guidance has drawn unusual attention in recent years: the suggestion that parents should include consent when changing a diaper.

The idea surfaced in Australia in 2018 and surprised many families. People wondered how a baby who cannot speak could take part in such a decision. Some even voiced strong frustration online. But two researchers from Deakin University, Dr. Nicole Downs and Dr. Katherine Bussey, are now explaining why this early approach to consent may matter more than it first appears.

Their view is simple. The goal is not for a baby to answer with words. Instead, parents can use moments like a diaper change to introduce concepts of consent, boundaries, and bodily autonomy. These early lessons may help children understand safe touch and personal limits as they grow.

The researchers say parents can start by slowing down. Get down to the child’s level, explain what needs to happen, and pause so the baby can take in the moment. Parents can offer small choices, such as walking or being carried to the changing area. Watching a child’s body language or facial expression can also help parents understand if the child is comfortable.

They also advise keeping the interaction clear and free of distractions. Saying each step out loud—such as asking the child to lift their body—helps them stay aware of what is happening and teaches them that their body deserves respect.

According to the scientists, these habits are not about complicated rules. They are about giving children the language and confidence to speak up if something feels wrong. At the same time, they stress that parenting is demanding, and no one will get it right every time. Even small, steady efforts can help build trust and support a child’s sense of safety.
