How much do newborns retain of their numerous sensory experiences inside the womb? There has been plenty of research into this topic. One study has found that, newborn babies indicate a preference for the smell of their mother’s amniotic fluid. In addition, by regularly giving an expectant mother a particular flavour to consume during the final two weeks of pregnancy, one may observe a clear preference, or at least tendency, in her newborn baby towards this substance, for at least a few days, or even weeks (studies showed a preference for aniseed, vanilla, chocolate, carrot and even garlic). We can relate this effect to Proust’s famous episode of the madeleine, which found that the olfactory bulb and taste system are in fact closely linked to the cerebral systems responsible for emotions and memory.
