6 to 12 Months: Your baby has much better control over arm and leg movement. By 9 to 10 months, your baby should be able to move around by some means- either pulling, crawling, or scooting. By 12 months they should be able to stand by themselves and many will even start walking. Educational toys including wooden blocks that baby can stack and knock down, throw, or bang together to make noise are good choices. By 12 months, educational wooden blocks can be used for early construction play to promote development of motor skills, cause and effect, sensory and visual stimulation. Educational toys like the Sensory Ball from Edushape, provides great stimulation with different textures. Once babies learn to sit up, they will enjoy rolling a ball and trying to catch it as you roll it back. Letting your baby chase the ball will encourage movement. Trying to figure out why a square block wont go through a round opening will help develop problem solving skills- though it may cause some frustration in the beginning. By the time your baby is 12 months, they will start to enjoy stacking activities, though they will need help in trying to get the right order. More interest in books will be noticeable now. Try to buy books that have pages with different textures and simple flaps. This will help to develop their sense of touch.

Teaching profession is devalued in the country because the teachers cant compete in our society, have no muscle power, are educated and hence behave differently. Neither do they have guts of creamy bureaucrats nor institutional support of any kind. A teacher can entertain you with a pale smile on hearing that this is the profession of nation builders, the cream of society and a noble profession. The next moment teacher will be branded as cancers in societal marrow, getting salary for no work, craving for power, equality in salary and status with the Class A government servants. The teacher was the consultant and conscience keeper of society till mid-century. One could identify him by his tattered clothes, emaciated pale face, soft voice and meek behavior. He was the guru. That guru, comparatively having a better outfit now, has metamorphosed to a present teacher.
