Her impression that she had six months within which to change her mind, as she testified, is entirely credible. On that state of the record with respect to the consent, it was incumbent on the adoptive parents to establish that the natural mother was not fit to raise her child (see People ex rel. Scarpetta v. Spence-Chapin Adoption Serv., 28 N.Y.2d 185, supra; Matter of Anonymous, 41 A.D.2d 961, affd 33 N.Y.2d 541; cf. Matter of Sanjivini K., 47 N.Y.2d 374). They declined to attempt to do this at the proceeding brought by the natural mother to obtain custody of her child, which followed the hearing on the consent. There is nothing on the record that establishes that the 25-year-old natural mother, a registered nurse, is unfit to raise her child.

Listed are recent decisions which permitted revocation of "consents" to private adoptions. (Matter of Anonymous, 41 A.D.2d 961, affd 33 N.Y.2d 541; [time not stated; parent found fit]; People ex rel. Ferro v Bacile, 35 A.D.2d 550, affd 28 N.Y.2d 537 ["soon after"]; People ex rel. Kropp v Shepsky, 305 N.Y. 465 [14 days].) Revocations of "consents" to private adoptions were denied in the following decisions.
