DS is only 2.5 but chooses what he wants to wear. Unless we're going somewhere special, in which case, I'll give him a choice of two things so he's still choosing. He's not interested in much else yet thank goodness. But yes, if he was interested in a particular haircut, I'd probably say yes, within reason of course, I've already decided I'm not going to pay for my kids to have colours in their hair etc - mostly cos it's too darn expensive (and I don't have it).

Re piercings, Mum told me 13 to get mine done, then I bugged her too much and she made it 15 (she doesn't remember this). I then discovered I'd have to pay for it myself (lol) and didn't get it done til I was 20. Never regretted it.
