Hello divit
Your son lagna is in Aries at 17°36’6″ co-ruled by Mars-Venus-Mars. Mars is in lagna. Venus is signifying 11th house through Moon in 11th house. Moon is in Pisces at 0°34’48” co-ruled by Jupiter-Jupiter-Mars.
His 2nd cusp (speech) sub lord is Saturn. Saturn is signifying Moon in 11th house (labha sthana) Pisces which is a watery sign. Saturn is signifying Moon through his sub lord Rahu also. Rahu is the significator of 2nd house. As it is not connected to 8th house (defect), there won’t be autism. He will speak slowly. Saturn is a planet for slowness. Watery sign is a mute sign. Mute sign gives the sound very less. He will be reluctant to speak. So the child does not speak as you expect from a growing child.
Again Saturn gives slow and steadiness. Moon gives imagination and fastness. In the connection, Saturn hinders the movements of Moon. He will not deny, but delay things.
Defect : 8th cusp sub lord is Mercury. Mercury is connected to 11th house through Moon and 8th house through Ketu who is in 8th house. This Ketu is signifying 3, 10 houses. 3rd house is for hearing, 8th house is for sickness to hearing (3rd house – initiative to move with anybody also) i.e 6th house from 3rd house, and 10th house is 8th house from 3rd house, i.e defect , sickness to hearing. I hope because of these things the boy is unable to speak. Kindly verify these things and consult the ENT surgeon.
Saturn, Jupiter, Mercury, Venus and Sun are in 8th house from 3rd house. Even they are in 10th house all are connected to Moon in 11th house. Sun is the only planet who is in an airy sign (a voice sign).
Current dasa: Saturn-Saturn-Mercury is upto 08-05-2025. Next comes Ketu and Venus antaras which are upto 9-1-2026. So in Saturn dasa-Saturn bhukti-sun antara the boy would start speaking.
Good Luck
