Pt 5 Are prepubescent children e.g. those dying before they commit actual sin, saved?

Gavin says, "in this Part 5 … we shall consider 4 points about 'children dying before they' are old enough to 'commit actual sin'… . 1stly, both original sin & original guilt means that Christ except, every human being is worthy of hell; & that God created men to have intrinsically mortal souls, so that for a soul to live forever requires that either God gives a saved person the gift of everlasting life or God sentences a damned soul to eternal punishment; & that there are degrees of punishment in hell which at the lower end is punishment followed by soul annihilation which I understand to be the judgement for unsaved 'children … dying before they commit actual sin,' & at the higher end, there is eternal punishment. 2ndly, we cannot look to the 'fruit' in the lives of 'children dying before they' are old enough to 'commit actual sin,' to see if they 'are … saved.' 3rdly, in harmony with Reformed teaching, if they are elect infants, dying in infancy, 'they … are undoubtedly saved.' 4thly, God only allows the prepubescent children of Christian believers to die if the children are heaven-bound elect vessels; & God only allows the prepubescent children of non-Christians to die if the children are hell-bound non-elect vessels." "Part 5 & … Part 6 are to some extent connected by the issue of baptism, … in Part 6 we shall ... consider …, Scripture teaches that Christian parents have their children baptized, & so understood as an evidential fruit of obedience to God on the matter of infant baptism by orthodox Protestant Christian parents, as a general rule, one may say on the basis of 'God's Word, that' prepubescent 'children which are baptized' who die … '… are … saved'."
