Your children will grow up and move away someday. You want them to be independent individuals that call you because they want to, not because they need you every step of the way in their new lives. Believe it or not, not every parent knows how to help their children be independent individuals. They don't know how to let them cut the apron strings. Cutting the apron strings doesn't mean that you never get to see their kids again; it simply means you are allowing your children to be their own person, learn from their own mistakes, and make their own choices without your influence unless they ask for it. It is important step in your kids' lives. It is the entry from childhood to adulthood and you can help them prepare for it from an early age. In each stage of your child's life, there are ways you can help them be a little more independent, to think for themselves, but still respect your opinion.
