• During the first few weeks, baby will be lying with her head on the side, since her neck muscles are too weak to hold it straight, and since she can’t look straight ahead, there is no need to install the moving mobile part for the first two or three weeks.
• The music alone, however, offers an excellent development aid.
  It's advisable to install the turning mobile by the fourth week.
• This will encourage baby to straighten her head and look toward the mobile overhead.

• With the onset of binocular vision and depth perception, baby can now enjoy the full breadth of the mobile, and can enjoy it from a distance.
• Baby will enjoy the falling beads, and follow them.
• She sees how the toys are organized – from the bottom up, and from the top down, which contributes to spatial perception.
• She enjoys the disappearing and reappearing objects, as she begins to understand object permanence.

• When the turning mobile part is removed, the music box becomes a musical activity center, and baby busies herself with games of trial and error, as she uncovers all the wondrous possibilities – like pressing the buttons to produce music, how to switch tunes, and how to turn it off.
• This is an all-in-one lesson in cause & effect, and a great exercise for developing fine motor skills.

Playing with this toy

• After the sixth month, babys often lie on their backs, raise their legs and lean them on the side of the crib. They may inadvertently turn on the music. This unintentional activity could become intentional indeed, as your baby learns to understand the result of her actions.
• Show your baby how to turn on the music box, and encourage her to try it herself.
