Children under 5 years if don't listen what to do about it?

Be patient, watch : I assume you re talking about toddlers who can t follow directions. It is normal for kids to not be entirely obedient or disciplined at such an early age. Their instict makes them explore, touch, experience the world, independiently from adult s opinions. So many times all you can do is make sure those adventures are non dangerous. Keep them safe and watch them.
