notpashut,
I am not saying to say that you think evreything is wonderfull obviosly you can tell your kids your opinion on things
just be carefull not to bring proofs that simply arnt good (like much of the “scientific” proofs to the torah)
or say things that arnt true (such as this is the only way to really be happy in olam haza Ect.)
as this can severly diminish your credibility and leave your kid very very dissillusioned.
