scroller: interestingly, the Amorah who takes a cacalier attitude to feeding one’s children is “ROVOH+ and this is the samew “ROVOH” who is the only Amoiro in Kessubos who takes the attitude that you can allow a father to let his kids be reliant uopn tzedakah. He is consistent but all other Amoroim have different views on that.. However, as you noted, that is aggadata and we are bound by “halacha pesukkhoh”. Rambam, Tur , Shulchan Aruch, all say that there is a full obligation for fathers to feed their small children-till six- and the “takkono’ is for children until they grow up.
I am not sure whether I want to repeat the arguments pro and con kollel on this thread. The gemoros that you mention and the Rambam are for very special and unique people,not for the klal.
