S.Q.
Sorry that I don't have more info, but I do know one family from PR and they are lovely, kind, down-to-earth, hard-working people. I think you will find good families everywhere you go, but I know that it can be off-putting when someone notices your nails rather than the fact that you are raising kind children.
Hey, if PR doesn't work out, consider joining us in Oak Park! I haven't had my nails polished in years (aside from when my 9 year old does them for me- hot pink at the moment!) and no one at the nursery school ever noticed!
If you move there, seek out families who share your values. We joined a board of an OP non-profit in our first years here and met some super-cool, dedicated couples who shared our love of kids and peace. Our nursery school was a relaxed, play-based school filled with families who were generally relaxed and play-based themselves! I met a lot of women doing fundraising for them, friends years later. I tried out the local women's guild, which was interesting, but not the best match for me, but it could be for you. Baby-sitting co-ops, playgroups, classes, kids' museums, and playgrounds are also good places to meet young families.
Good luck with your move!
