Child complains about everything
Q: How to educate & Counsel a child who complains about everything?
Focus on their conquering the sin of complaining. Teach why we are to be content and grateful. This may help.
Additionally this has a study about God's attributes; kids need to understand who He is, His holiness, and our life purpose so we can live rightly (as God designed us in His Image) to do.
This also points kids to the Gospel & our need for Jesus, so we can obey God and live in righteousness, [noting that while not perfect we're to be "growing" to be more like Jesus].
Adapt the information, for explaining and teaching these, to their age appropriate level.
