Hi,
Given birth-details of the elder child place Ascendent or Udaya Lagna in the Zodiac sign of Libra or Tula Rashi. Lagna lord Venus/Shukra placed in his Neecha-Sthana or sign of debilitation is not a good sign.
The child is currently in the midst of Ketu Maha-Dasha. He is placed in the 4th house of Homely Comforts and co-lord’s the 2nd house of speech. He is conjunct Mars/Kuja, the other co-lord, who is placed in his Uccha-Sthana or sign of exaltation. More importantly, Ketu is close to Mrityu Bhaga and with the fatal Trimsamsa degrees has probably contributed to Speech issues. Antara is that of Lagna lord Venus/Shukra placed in the 12th house of Vyaya/Losses/Hospitalization/Medical Expenses etc.
For the records, transits starting with Sade-Sathi or Saturn/Shani-dev’s transit across natal placement of Moon/Chandra has probably made the situation a bit more acute.
On the sidelines, there is indeed a strong indications of Pitru Dosha – as called out by respected and highly regarded TKC, which seems to be affecting multiple facets of the native’s life – including health, education, etc. So, it might not be a bad idea to consider seeking help and guidance from knowledgeable/experienced experts to perform dosha nivarana puja or suitable Vedic/Dharmic remedies.
Pitru Dosha is supposed to be associated with Karmic debt of ancestors, involving their past misdeeds, an indication of unsettled souls, unfulfilled desires etc. Please consider a quick/simple Google search, to get some understanding of Pitru Dosha.
Take care…
