In the above chart we see that the lagan is Meena or Pisces. Rashi is Gemini. Mars is the planet of energy, it makes the person aggressive, bold, courageous, we see Mars in lagan that is why your child is hyperactive. You need to find ways so that is excess energy is utilized positively. In his chart we see Moon is under kemdruma dosha. Mercury is in the 8th house in Rahu nakshatra. He is under Rahu mahadasha and presently Rahu is in the Lagan as per his Transit/ Gochar kundali. He will talk but after delays. Some medical help, therapy may also be needed to expedite results.
Make him wear a moti in a silver pendant on Monday during the period of Shukal Paksha. Also, every Saturday, donate something from his hands.
