Very helpful post. From 1st year to 7 year is very important age of children for learning. We should have to give special attention to their learning and character building. Specially when they reached at age 3 we should prepare them for schooling. For this purpose, I concerned with a website for my three years daughter by preschool activities. It helped me a lot.
