the idea mewho, if you would stop and think about it, instead of immediately being critical, especially without adding anything helpful of your own is:
to associate something that one is always carrying (ie purse for many women) and would sense it missing immediately,
to associate it with something (baby) that is NOT always present, especially for men.
people are human, sometimes they are preoccupied with worries or other things, some people intensely preoccupied, mistakes happen, even deadly ones, it is a shame, it is a tragedy. and if people need help tp prevent it, then they should avail themselves of it.
