Swetha ji,
Thank you for confirming the time you realised your sons speech delay!
Giving the period Jan to May 2025 to be a breather opening to your sons improvment in communication; albeit with sustained effort from June/July 2024.
For further details, since I do detailed analysis by blending Astrology, Numerology and Palmistry, you may opt for proper consultancy, where you would be guided/assisted in the process. You may check my profile.
