An Observation and an Explanation

It is worth looking at one or two aspects of the way a mother behaves towards her baby. The usual fondling, cuddling and cleaning require little ment, but the position in which she holds the baby against her body when resting is rather revealing. Careful studi es have sho

wn the fact that 80 percent of mothers hold their infants in their left arms, ho lding them against the left side of their bodies. If asked to explain the significance of thi s preference most people reply that it is obviously the result of the predominance of right -handedness in the population. By holding the babies in their left arms, the mothers keep their dominant arm free for manipulations. But a detailed analysis shows that this is not t he casE True, there is a slight difference between right-handed and left-handed females。 b ut not enough to provide adequate explanation. It emerges that 83 percent of right-handed mothers hold the baby on the left side, but so do 78 percent of left-handed mothers. In other words, only 22 percent of the left-handed mothers have their dominant hands free fo r actions. Clearly there must be some other, less obvious explanation.

The only other clue es from the fact that the heart is on the side of the mother’ s body. Could it be that the sound of her heartbeat is the vital factor" And in what way" Thinking along these lines it was argued that perhaps during its existence inside the bod y of the mother the unborn baby get used to the sound of the heart beat. If this is so, th en the re-discovery of this familiar sound after birth might have a claiming effect on the infant, especi

ally as it has just been born into a strange and frighteningly new worlD if t his is so then the mother would, somehow, soon arrive at the discovery that her baby is more at peace if held on the left against her heart than on the right.

16 We can learn a lot by observing the position in which a mother holds her baby a gainst her body.
