Your unborn child is growing physically, mentally and physiologically, with all the five senses developing during those months in the utero. You may liken the womb interior to a dark cave of quiet water, and yet wonder how the five senses of a real individual develop acutely from the embryo stage (size of a tadpole). While still in the womb the unborn baby with all its organs in place will breathe, move, swallow amniotic fluid, react to stimuli and prepare itself for life outside the womb. The learning and conditioning that happens in the nine months are crucial.
