We are traveling with a 4 year old SFO-SIN-VTZ. SFO-SIN-VTZ is very convenient on Singapore Airlines on their non-stop morning flight SFO-SIN with a short layover in SIN before connecting to SilkAir for SIN-VTZ. They are adding a second non-stop SFO-SIN flight soon, but that flight would result in a 12 hour layover in Singapore. (Sightseeing / long layover in SIN is not a bad idea with little kids, IMO). Could that be an option for you, even though there's an extra stop in the US? You could purchase a single ticket and check your bags all the way through.
Net net, you cannot get to VTZ from SEA in less than 2 stops (one here in the US or in India plus one in the Airline's hub), but you can minimize inter-terminal / inter-airline transfers and associated hassles. I personally like the idea of flying directly into VTZ in India vs. transferring in HYD/BOM/BLR/DEL.
