I grew up in NY and am now raising a family in E”Y. From what I know I wouldn’t say that it’s harder to raise kids here per se. Just that it’s different because of the differences in society.
There are many similarities between raising kids here and in America. The kids have their own version of fashion trends here that are taken to a level I never saw before. On the other hand even the most trendy she’b’trendy here can probably do a blatt gemarah with reid. Which is much less true of America.
I one time sat in on a nice halacha shiur given by (I think he was) a bochur in shul on friday night between kabbolas Shabbos and maariv. He had a chup 3/4 the size of Florida and I’m not over exaggerating. He probably has to call in the IDF to help him comb it out every erev Shabbos. But it was a great shiur.
The hardest things to adjust to is the chutzpah here which is notorious. Not just in kids, they learn it from the pros. It takes a long time to adjust to for some people. I’ve noticed though that usually the children of Americans are better with this than pure-bred sabras.
Every place has its ma’alos and chesronos in raising children. You need to shatz them all up and see which ones you can work around or accommodate.
