Just that really. I'm sure when I was a kid my parents' bedroom was basically off limits - ie I had to knock before I went in, there was no open door policy. My own DC (8 and 6) just wander in to ours at will, jump around when I'm trying to get dressed and so on. Obviously when they were tiny it was one thing but I find it a bit grating now, I would love just one space in the house that is adult only! Do others accept their kids wandering in and out or is this something that people clamp down on when they outgrow the toddler stage? My parents were quite hands off and I don't want to be like that.
