Help! My ds (6mos) is rolling all over the place- front to back and back to front. It is adorable when he is excited about it, but it seems like he can't stop himself, and then he get really upset and frustrated. It is disrupting his naps bigtime, and then as a result of his being overtired I have a hard time getting him down at night. Any thoughts, or ideas, or just tell me it will pass!!!
