Your baby's 17th week
Look out! Your little one is now able to accurately track objects with his eyes and grasp them with both hands. His eyes are maturing and he'll begin to have improved depth perception and generally clearer vision. He'll delight in pulling dangling objects. Favorite items are sure to include your hair, jewelry and clothing.
Keep your ears tuned in as he learns to laugh. Great big belly laughs are wonderful to hear. Elicit a few by tickling him and watching him squirm and giggle.
You'll notice him turn toward a voice when someone speaks to him. It will be increasingly easy for him to do this as he props himself up on his arms when he's placed on his tummy. He may even be able to rest on his elbows. Be sure to supervise him closely when he's on his tummy and remove pillows and soft bedding from his reach.
