"Anybody seen my baby?" is a song written by the Rolling Stones. It is about a man who is looking for his girlfriend or "baby" because he misses her and wants to be with her. The song is sung in a sad and longing way, with the man asking anyone who might have seen his baby to let him know where she is. It's like when you lose your favorite toy and you ask your parents or friends if they have seen it so you can find it and be happy again.
