Your baby's seventh week
Motor skill development is prominent at this age. Watch as your little one discovers he can move his arms! He'll begin to swipe aimlessly. Though he doesn't yet have the hand-eye coordination, or necessary muscle tone to effectively reach for an object, he'll most likely squeal in delight as his arms flail about in the air above him.
Current recommendations direct parents to place infants on their back for sleep. This position can reduce the risk of Sudden Infant Death Syndrome (SIDS) and accidental suffocation. This also offers your little one the opportunity to gaze at a mobile dangling overhead. He'll enjoy some "tummy time" too. Try placing him on his tummy throughout the day when you are able to closely supervise play time.
When selecting toys, keep in mind he'll most likely prefer black and white color. This may seem somewhat monotonous to your fully developed eyes, but he'll enjoy in the simplicity. Classical music is also likely to be a favorite. Pick your favorite composer and introduce him to the variety of upbeat, relaxing and playful melodies. You don't have to stop there. Gradually introduce him to your favorite contemporary artists as well. Be sure to keep the volume somewhat low and watch his reactions closely. If you find a particular type of music upsets to him, try changing the tune.
