In the US, all locks must be openable from the inside. Here in Israel, most locks are designed so a key is needed to unlock the door from either side. If the key is still in the lock on the inside, it’s impossible to get into the apartment without breaking the lock. Many a babysitter has locked the door, left the key in the lock, and fallen asleep, forcing the parents to climb in through the window. When I moved to a new apartment, I paid an extra NIS 20 ($4-$5) to get a lock that allows easy exit without a key and entry with a key.
Just a few weeks ago, a neighbor suggested I leave my 2yo at home after I complained that she would be asleep during the gan pickup time. Unfortunately this attitude is still too common. The neighbor said that she had done it all the time and she “had no choice.” Since when is waking up a child not an option? Another child was killed a few years ago when a babysitter left an infant and a six-year-old home alone to pick up a third child from gan. The infant crawled under a stroller and strangled himself. It was raining that day and I’m sure the babysitter didn’t want to inconvenience the children by taking them outside. I wonder if the babysitter had told the mother of her plan.
