My in-laws live in Seoul and visit us about once a year. Our relationship is fraught and complicated, but (hopefully) improving with time. Regardless, they love our two sons and I know they try their best to be good to us.
When my first son was three months old and I was returning to school to finish my last quarter of undergrad, my mother-in-law pretty much offered to take him to Korea with her for the next three months. She was worried I wouldn't be able to handle a baby and school. I, on the other hand, was so appalled at the very suggestion of living an ocean apart from my infant for three months that, in my shock, I blurted out rudely, "I would never do that!"
Fast forward a few years and now we have two sons who are four and nearly two. Every visit, my in-laws drop hints that in a few years they expect us to send the kids to Korea for the summer to stay with them. I know that, as much as they want to spend time with the children, they also think of this as a generous way of giving us a much-needed break. But, much as my reaction to my mother-in-law's initial offer so ungraciously showed, I still have a hard time wrapping my head around the idea. As much as I think that spending a summer (or summers) in Korea would be a wonderful experience for my kids, I still can't imagine sending them anywhere without me. I can barely leave them overnight at my parents' house when Yubo and I manage to plan a night away for necessary romantic purposes. And not just because I miss them, but because they seem insecure and overly irritable for days afterward.
Is this just me being overprotective and overly attached? Perhaps. But, to be honest, I'm comfortable with that. Even if the idea of a whole summer without the kids is mildly tempting (freedom!), I'd still much rather spend that time with them than without them. And as someone who tries to practice attachment parenting, I have a hard time believing that young children benefit from being away from their parents for extended periods of time. I know that there are plenty of Korean American kids (including some of my friends growing up) who spent summers with relatives in Korea and they turned out fine blah blah blah, but I'm still not sold on the idea.
