An amniotic infant blanket provides a feeling of fluid warmth coupled with the audible sounds of a human heartbeat. Behind a head or face portion of the blanket, a pocket is provided into which a bladder may be removably inserted. The pocket may be sealed by a zipper and has an aperture through which a hydrophone wire may pass. Likewise, the hydrophone wire may pass through the wall of the bladder without creating a leak therethrough. The bladder is filled with lukewarm tap water and the hydrophone connected to a playback unit that transmits signals that are transformed by the hydrophone into heartbeat sounds with which the infant is familiar.
