Zero is a pesky little number. Left alone it equates to nothing. But, placed at the end of a number it increases value.
Life is a little like the number zero. Besides the love of your family, you enter the world with nothing. Eventually, you acquire knowledge, education and physical resources—life experience. Throughout life we have good times and bad times; all of it adds up to our strings of nothings and somethings that make our lives meaningful.
Make every second, experience and sensory stimulation count for your child. Everything is a learning experience; take advantage of it.
