The IL's will help. But only if it's convenient for them. When we have asked for help, their social life is always more important so now we just don't bother. And on the odd time it was convenient, it always turned out to be more work for us (would only help if we took them there etc) which if you're sick and can't get out of bed, isn't much help!! So we didn't bother following through.
I feel sad for my kids. My grandparents were great! I will be using them as my example of how to be a grandparent. My kids might be missing out, but my grandkids sure won't.
