Worn joints. Just like the other joints in your body, your neck joints tend to wear down with age. Osteoarthritis causes the cushions (cartilage) between your bones (vertebrae) to deteriorate. Your body then forms bone spurs that affect joint motion and cause pain.
As the user guide explains, kids hardly read (and you canât expect a 3 year old to read!). So you get games which teach you about letters and numbers starting from the real simple ones to others that teach more fundamental things like reading time or guessing colors.
Your baby may even begin to recognize a song or rhyme if you repeat it often. By the time she is 4 months old, your baby will show an interest in books and start to explore them by chewing or throwing them. At this age, your baby needs sturdy vinyl or cloth books that can survive chewing and are not easily torn.
