children_slice_get behaves in two different ways, it may
provide the slice if both $start AND $count are non-zero

slice could be the range from 3(start) to 4(count), see:
child 0 [no]
child 1 [no]
child 2 [yes]
child 3 [yes]
child 4 [yes]
child 5 [yes]
child 6 [no]
child 7 [no]

number of children so a valid range can be known in advance.
