Which gemstones, colors, or elements can help my child stay calm and focused?

Namaste, Maine notice kiya hai ki mera bachha kabhi-kabhi restless ho jata hai ya easily focus lose kar deta hai. Mujhe yeh jaana hai ki kya unke astrology chart ke hisaab se koi specific gemstones, colors, ya elements hain jo unhe calm, balanced, aur focused rehne me help kar sakte hain. Kya aap guide kar sakte hain ki unke energy aur concentration ko support karne ke liye kya best rahega?
