Hi,
Given birth-details place Udaya Lagna or Ascendent in the Zodiac sign of Cancer or Karkataka Rashi and Lagna Lord Moon/Chandra is placed in the 12th house of Vyaya/Losses/Hospital or Medical expenses. To make matters worse, low-profile miscreants Maandi & Gulika are hoovering around Moon/Chandra, who does not have any support on either side of the flanks (making the developing brain to wander aimlessly. This could also contribute to limited ability to focus) and more importantly he is placed close to Mrityu Bhaga and within the fatal Trimsamsa degrees (as per Phala Deepika and Brihat Prajapatyam). Further, he is posited in the Lunar Constellation of Ardra Nakshatra, ruled by Rahu. So, the little one started his life in the midst of a Rampaging or difficult Rahu Maha-Dasha (as per Vimsottari Dasha system), lasting until second half of 2032.
Just so you are aware, your son was born in the midst of CoVID-19 pandemic and from an Astrological perspective I’ve shared my understanding of how the planets aligned to precipitate matters after the fateful eclipse and how Rahu went on a rampage. So, I’d suggest that you not panic and be very calm/patient, while monitoring the child’s physiological development and well being. If need be, please consider getting a physiological/psychiatric evaluation done.
Secondly, the child was born in the immediate aftermath of a partial Lunar eclipse (18th-19th November) and before a total Solar eclipse (4th December). So, Sun/Ravi the second lord of Speech and natural or Naisargika Aarogya Karaka was also caught in the Rahu-Ketu axis, rendering him weak. He has the least Shadbala. Mercury/Budha seems to be too close to Sun/Ravi for comfort…. and seems to have been torched. He being placed in the midst of all Krura Graha or Malefic planets is not a good sign… and perhaps a sign of delayed/diminished communication skills.
In summary, I’m inclined to think the problem is much more than delayed speech… for instance, I’m inclined to think the child’s parents are not experiencing the best of times either.
Take care…
