For many of us whose children are still little, the thought of them ever flying the nest can strike fear into the heart.
But what if they don't fly the nest? What if our kids don't move out at 18 or 21 or even 25? What if house prices continue to sore to such an extent that leaving home just isn't a viable options for our children once they're of an age to start an independent life?
At this stage in my family life that's not a particularly scary notion - I'm definitely of the opinion that I'd quite happily keep my babies at home forever.
But the latest data suggests that I should perhaps be worrying a little more about the possibility of my kids still living at home in their twenties and even later still.
This Is Money reports:
There are now 3.3million 20-34 year olds still living with parents, a 618,000 leap since 1996, the findings from the Office for National Statistics show. A fifth of 25-to-29 year olds still living with their parents, and half of those aged 20-to-24 and one in 10 aged 30-to-34 are also in the same boat.
I see little point worrying about what's still decades away in the future but at the same time I find myself wondering if I ought to be a little more money-conscious when I read headlines like this. I haven't yet managed to get a foot on a rung of the property ladder myself and I'm ok with that - there are benefits to being a renter such as not having to shell out to fix the fence when it blows down in a hurricane.
But maybe I should be less blasé about things and should be trying to squirrel away more cash for the my children's futures? Only problem is, there isn't much disposable cash to stash away for the rainy days that might lie ahead.
We'd love to hear how you feel about this data - do you worry about your child not being able to afford to leave home in the future, and does it motivate you to save towards the things that your child might not be able to afford when they reach adulthood?
