Have you looked up the word in a dictionary?
Student or Learner
Could you please help me to understand the meaning of the word "Judgmental" in this context.
If you are judgmental then your children may not be truly open with you.
Yes I did, but want more explicit meaning of it.
If you make statements about whether what they did was "right" or "wrong" or "good" or "bad" (especially "wrong" and "bad") they won't want to tell you things.
That was stupid!
You were foolish to do that!
What a terrible thing to say!
Only a really mean child would do what you just did! You should be ashamed!
Would you want to talk to someone who said that to you?
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
