I would like to add that things get easier as other kids get more verbal (though they don’t “catch up”) and that having a parent who “gets it” and is proactive in finding other people who “get it” will go a long way to make things easier fir our kids than it was for our generation.
It is hard work but my kids are doing so much better socially than I or my husband ever did.

And, and I hope you won’t be offended by my going there, the best thing you could provide for your daughter asap would probably be a sibling....
