• 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.

• The white cone and black rings offer sharp, contrasting visual stimulation to focus on.
• Baby will focus on the moving objects and follow them, as they appear and reappear from her field of vision.

• With the onset of binocular vision anddepth 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 spacial 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 and effect, and a great exercise for developing fine motor skills.

Playing with this toy

• Babies at this age 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.
