I think this is more a reflection on you, than anyone else.
You're essentially saying YOU and your children struggle to have fun without spending a lot of money.
That's actually quite sad, in the 😞 way.
We don't struggle for money, we travel a lot, dd has an array of hobbies, we don't watch what we spend - if we want it, we buy it, and my nails are always done.
But we also have a lot of fun doing things that cost very little, and always have. We could eat well, and have a great time on £540 for three weeks for three of us.
It's the people who make the fun, not the purchases. It's a shame you don't know how to have fun with your kids without spending money. They're going to grow up thinking happiness is material.
