Yes this does happen
Happened to me in the hospital when i had DS cause he was in special care i wsnt in my room much and they took my wallet and lifted $1000 from my bank account, my mobile phone and my camera (all my newborn photos were gone) My house had been done the week before (on DS due date) so sorry home birth doesnt rule you out, lost my wedding engagement and eternity ring which turned up in cash converters. Yes it does really suck but i had DS to cheer me up
