I am looking into a Jewish daycare for my new baby..
The daycare is on a site which includes a synagogue, rabbinic college, reform judaism hq plus the nursery. Coincidentally I visited the site 4 years ago as it also has a mikveh which I immersed in as part of my conversion requirements. There was a guard but I don't recall the level of security that it currently has..
Not only is there a guard at the gate, but you have to sign in on an iPad and a sticker with your photo is autogenerated. You have to wear the sticker and when you leave, the security guards makes sure that the sticker is disposed off. It is literally tighter than airport security.
Tbh this isn't new, my dh is from the same school those kids went to and he said kids from a nearby school used to throw pebbles at his window too. It is a very fraught difficult situation, my dh still has a lot of sympathy for the palestinian cause despite the way he was treated which is different from many of his peers who are ardent zionists. In a sense people like him are the loneliest.
