Ambika was sent by Satyavati to Vyasa a second time, due to the first one being blind. It's a different issue that she sent her maid instead, b'cos had she been more accustomed to Vyasa by then and gone, she'd have had 2 children from Vyasa. So was there an exception - like if the first child was disabled?
Ummm...yes, you have a point here. AFAIK, disability, per se, should not be an exception. The exception if any, would be if a girl had been born out of such a union- since the paramount reason for resorting to Niyoga was to produce a son who would continue the lineage.
Actually I cannot understand Satyavati's motive here in sending Ambika a second time to Vyasa.
While Dritarashtra though blind, could still perform his father's (and eventually, his mother's) after-death ceremonies. So the main purpose for resorting to Niyoga was achieved.
Even if a healthy child had been born to Ambika, the second time around, that child would be younger to Pandu, and hence only second -in - line to the throne, after Pandu.
