We have misunderstood the abilities of babies. They are not simple beings but complex and ageless, small creatures with unexpected big thoughts. Babies know more than they were supposed to know. After only minutes of repeated exposure to its mother's face after birth, a baby can pick her out from a gallery of photos. Babies recognize the gender of other babies, even when cross-dressed, provided they are moving-something adults cannot do. They are curious and eager to learn. Through scanning electron microscope, ultrasound imaging, and other measuring devices we now have a picture of development of all parts of the physical system before birth. These discoveries have added to our understanding of the talents of baby. Neuroscientists have discovered the timetable for the development of nervous system. Recent studies show that the sense of taste begins functioning around fourteen weeks after conception, and the sense of hearing around twenty weeks.
