Babies do not know Christ though Christ knows them. So does God grant salvation to babies who have died before accepting Jesus Christ as their saviour?
Certainly...(the knowledge of) The Law brought sin...Where there is no knowledge of the Law, there is no sin...
Rom 4:15 Because the law worketh wrath: for where no law is, there is no transgression.
A baby or child has no knowledge of sin, therefore will not be judged as a sinner...
