The age when you say no to kids is around 2 years old which is when most kids start to understand the word no.
Before 2 years of age kids don't usually understand or get the word no.
But if the child or toddler is doing something they shouldn't be doing you should stop them and let them know that they shouldn't be doing what they are doing.
At around 2 years old, your child will also learn to say 'no'.
Your child may say 'no' and refuse to do things as a way to make their own choices.
They might also say 'no' to try and express difficult feelings that they don't understand.
You can help manage this difficult behavior by supporting them and giving them choices.
If kids never know where they stand or what response they are going to get from you, it can make them anxious and they can lose trust in you and your authority.
'Children always push for boundaries, they are pushing for those “nos” and it's our job to give it to them.
Also if you say the word "No!" to your child all the time, they may start to tune you out -- or worse, begin using it when they don't want to do something.
"Save 'No! ' for situations when safety is involved,".
Permissive parents are indulgent, focusing extensively on their children's emotional well-being.
They don't like to say “no” or disappoint their children.
They believe it's important to be friends with their children and fulfill their desires whenever possible.
Permissive parents might say, “I never say no to my child,” or “My child chooses what they want to do.”
Permissive parents struggle to set age-appropriate boundaries and instead shift decision-making to children.
