Hi,
It would help if you could kindly share details of the medical diagnosis, your observations of the child’s behavior, his cognitive skills and other development aspects. I would also appreciate if you could kindly provide some insight into the environment at home – quite frankly, there are a couple of things (including placement and influence of Saturn/Shani-dev, Jupiter/Guru-dev and Moon/Chandra in the birth-chart) that seem to stand out for me and the one with regards to home environment is a bit of a concern. You see the 4th house of Homely Comforts is caught between Mars/Kuja (Badha-Karaka) and Rahu, in a strong Papakartari Yoga.
On the sidelines, the child will be starting a decent benefic period, staring in a few days… hopefully, things should get better – not to mention dwindling effect of Sade-Sathi or Saturn/Shani-dev’s transit across natal placement of Moon/Chandra. That said, it should not hurt for you to consider reading/chanting or making the child hear Shriman Vishnu Sahasranama.
Take care…
