A soft cuddly baby with no batteries, no "extra" parts, nothing that can come off. The "babies" that do things need batteries, batteries can leak. When my dd was 3 I got her a doll that was motion activated. When you walked by it would laugh, or say "I love you" or "Pick me up, Mommy". She was terrified of it. She said, "Ebil ting, out my room!" Simple is better, it allows for growth of imagination.
