common belief is that it is dead relatives doting on the
new born, esp the grand parents
before resorting to talisman/idols, the next time it happen,
just advise/remind that while it is common for relatives to dote on
new borns, what they are doing may cause harm. hopefully, this
would solve the problem
I've also heard, that for some it's the baby's older siblings
that comes back .... abortion, miscarriage etc ......
