They're going to get exposed to ads whether I like it or not, and I'd rather they learned what they are, how they work and to just deal with and ignore them. You don't build up a resistance to germs by living in an antiseptic environment your whole life, and I think it's the same with ads. We make sure our girls have plenty of physical and mental activities to enjoy. Both of them love art and use our computers and iPads for drawing, sketching and painting as well as physical media. They're both musical playing the piano and flute, and occasionally play around with Garage Band and such but visual arts is their main thing. We encourage outdoors activities, they went horse riding for years but that's died off and they've both been in the Air Cadets here in the UK for about a year. To me it's about balance and encouraging responsibility.
We're very much guiding our kids childhoods our way, the choices we make for them open some avenues but inevitably close off others. That seems to be working fine for us, but I've got no problem with your way. They're your kids and I fully understand why youre taking the approach you are. I just don't think it's the only responsible attitude.
