I have decided recently that I won't buy stuff with skulls on it. Boys can be fixated enough with gross things so I don't want to encourage them.
Unfortunately, our small country town only has Target to buy clothes from and so many of the boys clothes are covered in skulls! It's really annoying.
I also love bright colours and my boys aren't quite old enough for the whole goth thing yet so they're happy to wear them but again, lots of the pre-teen stuff is grey or black or navy! No wonder our boys are suffering from depression! Ok - so there might be a bit more to it than the colours they wear, but still ...
I don't like the skulls on the (otherwise lovely) hot pink Smash Woollies waterbottles with covers.
And, while I've given in for Nerf guns and water pistols, I won't allow replica or any "real" looking guns.
So, what do you refuse to buy for your kids and how hard do you find it to stick to your guns (excuse the pun)?
