I read that there has been fewer than 400 home abductions in the last 25 or so years - so this is very rare.
I would think that an abduction from a home would be damn near impossible unless the perpetrator knew the people who lived there, had been invited into the home numerous times so that their kids and barking dogs were familiar with them, and knew every way there was into the house undetected-risky and troublesome to kidnap from a home-it would be easier by far to do it the way it usually happens-follow a mom to a location like a park, mall, etc snatch a baby from a a stroller while mom is distracted and vanish into the crowd. Fortunately, these people DO get caught-I pray this kidnapper does, too-no matter what happened, the poor baby needs to be found.
