“There is no cook book on how to raise kids. Good parents do fine without the manuals and bad ones founder about with them”
the way that true Jewish parents have raised their children has always been with the advice of their own parents, Bubbies, and Zadies and with the advice of the Chachomim, both the contemporaneous Chochamim and those of previous generations who brought down their Chachmah in Gemorrah, Seforim, and father to son, Rebbi to Talmid.
although today parents can not always use these sources, there are a number of “cookbooks” that have been culled from these sources that are available. i mentioned one above. there are MANY, MANY shailos that come up in raising children by true Torah Jews, and one cant always rely on “doing what is in the heart”, doing what feels right”. no one who understands what a precious responsibility a Jewish child is would act so irresponsibly.
of course i guess the in thing is “to each his own”
but if you want to raise Hashem’s child, get some Torah guidance
