Setting boundaries in parenting

Be trustworthy: Be true to your North
Set out few rules and avoid setting out several rules at any given time. This will avoid ambiguity and confusion.
Be precise Let the child repeat what you have said to ensure clear communication
participatory: Involve the kids when you are setting out rules
Write down the rules and stick them on the bedroom or kitchen walls
Reinforce appropriate behaviour. Do not show up when the child is always in the wrong
Do not brand the child as bad or good. Brand the behaviour either as acceptable/ unacceptable
Never undermine the other parent: Parents should back each other
Be consistent
