While your tween is beginning to develop their own identity and worldview, you'd need to balance parental guidance with giving them room to test their wings in the controlled and safe environment of home.
Help your tween expand prayer beyond self to praying regularly for others and the world around them. Help them expand their understanding of worship beyond singing praises to honoring God with their entire beings. There's no better inspiration they can have than to see their parents - you! - engaging with and growing in God.
The adolescent years can be rocky for both your tween and yourself, so pair parental guidance/input with plenty of prayer. Finding prayer partners and godly parents ahead of you in the journey can be of great encouragement.
