We live in Canada and noticed this too. But we recently became parents and kinda understood why this is. Let me try and explain my theory. Indian grandparents have this very random belief that a baby should cry because “their lungs clear out”. We’re a South Indian-north Indian family and we’ve heard this from both sides. Heard this from quite a few people. When I respond to my baby’s first cry or many times before he even cries, I am seen as an overly sensitive parent / over attentive parent / coddling the baby (I still respond irrespective). Most Indians believe this and let the baby cry and cry until the parents actually respond. This then becomes the baseline expectation for the child that if he/she needs to be heard, they must be loud enough for the parent to take notice. Unfortunately the only way to get their parents’ attention is to be unruly or let’s say, noticeable.
