Well, this is a very common scenario; in our neighborhood, there are probably 75 families that share this circumstance, and seem to thrive very, very well. From all I can tell, the Asian grandparent community just grows where they are planted. Literally.
A group of Chinese grandparents took land that looked like this:
[this actually looks pretty nice, but it's just random grass and weeds]
And turned it into this:
A beautiful garden, brimming with peppers, tomatoes, cauliflower, lettuce, and, well, a lot of Chinese plants that they can't find here. There is so much ingenuity in the garden maintenance: no wheelbarrows? Fine, just use a baby stroller! Ran out of buckets? Just use a food cooler. As I've watched our Chinese neighbors over the years, I've noticed how resourceful they are, making use of everything they have and I really admire that.
If we ever leave New Haven, I'll miss this tight-knit Chinese community. Not that we really hang out, but they remind me of my own LDS friends--we all love families, we stick together, we are [more or less] quiet and responsible neighbors (although I think our neighbors below us have had it up to here with our bouncy balls). And, when I'm strolling Pete around, I probably pass five or six grandparents with their babies, and we both give a knowing smile to each other that says "Your baby is beautiful. And isn't mine, too?"
