In Application of Gault, 387 U.S. 1, 55, 87 S.Ct. 1428, 1458, 18 L.Ed.2d 527 (1967), it was said: "We conclude that the constitutional privilege against self-incrimination is applicable in the case of juveniles as it is with respect to adults. If counsel was not present for some permissible reason when an admission was obtained, the greatest care must be taken to assure that the admission was voluntary, in the sense not only that it was not coerced or suggested, but also that it was not the product of ignorance of rights, or of adolescent fantasy, fright or despair."
