Poor daycare security? Should we be worried?

Today I picked up my one-year-old son from daycare for the first time (my wife usually picks him up). I was able to walk into my son's room, say I was there to pick him up, and the teachers gave him to me after asking "are you Dad?". No ID checks, and my wife hadn't said to expect me.The front desk staff at the daycare know me, and did say hello this time. But at least half the time there's no-one at the front desk, according to my wife. I'm worried that means anyone who knows the building code can walk in, go to a classroom, and take a kid claiming to be a parent the teachers haven't met.Is that how it usually works, or have we found a daycare with bad security? I asked the daycare staff, and they said "the teachers rely on the front desk staff stopping anyone they don't know" -- but often there's no-one at the front desk to do that, just a door with a code shared between all the parents at the 200-kid school. Are we being paranoid to be concerned by this? via /r/Parenting http://ift.tt/2jJkcUC
