I have always wondered why babies cry the second we sit down. Baby wearing is a lifesaver parents!!!

Hold your babies, people!! Preferably up,as far as the child is concerned & much to the dismay of tired parents around the world who are exasperated at an infant’s insistence at holding them standing.
A study by Esposito et al. (2013), published in the Journal of Current Biology,demonstrated for the first time that the calming response to parents holding them is a coordinated set of central, motor & cardiac regulations & is a conserved component of parent-infant interactions in mammals.
Using ECG to monitor 12 healthy human infants’ heartbeats, along with their behaviour & vocalisations, they recorded mother-infant pairs during behavioural tasks that consisted of the child lying in a crib, being held by the mother who was sitting on a chair ( ), or being held by the mother who was walking continuously ( ). The researchers found a sustained elevation of heart interbeat intervals due to carrying in awake infants could not be explained by any known cardiac vagal reflex, including the orienting reflex (brief period of heart rate deceleration by mild sensory stimulus),suggesting that carrying evokes a sustained heart rate reduction in concert with the rapid behavioural changes in human infants via a novel mechanism.
The researchers found that in mouse pups, carrying induced calming responses similar to those in human infants, even though maternal carrying methods differed. This draws parallels between the carrying-induced state evoked in human babies & other mammalian young such as cats or squirrels who adopt a still, compact posture with their hind legs drawn up when maternally carried. The reduced mobility, reduced distress vocalisations, & reduced heart rate appears to be adaptive.
The calming responses evoked by carrying are thought to be an evolutionary measure to increase the survival probability of the infant in cases of emergency escape by the mother & child &so ultimately works to strengthen the mother-infant relationship. There is adaptive value in this behaviour in carer-infant relationships & as a consequence , infant survival.
The study found that the effects of carrying on the infant’s parasympathetic nervous system were significant, and it provides a scientific understanding of this physiological infant response that could be beneficial for parents and early childhood educators to understand.
Considering the physiological response of the infant when being carried may lead to greater parent and carer patience, reduced frustration and an increased appreciation of age-old parenting techniques such as and parenting.
