The dolls have evolved since their introduction, and the foundation is now selling its third-generation doll, called "The Inner Child." These have a built-in recorder on which doll owners can record their inmost thoughts as they are growing up, then relive those experiences at a later date.
勵馨不斷地推陳出新，第三代的勵馨娃娃名為「內在小孩」，具有錄音功能，可以錄下自己心裡的話，讓人重拾成長過程中的點點滴滴。
