I found our house useful in the early years I could let the kids run around and still hear them. We had lots of space etc. But now they are aged 10-14 I have the issue of watching grown up TV downstairs and if one is still awake they can hear, come downstairs and see or watch from the stairs as there are no friggin walls. We only have bedroom doors between upstairs and downstairs. No walls or doors for the stairs, living/ dining rooms or kitchen. It means I am on edge. For instance tonight I started watching "sex education" on Netflix, lots of sex, swearing and phalluses and ds (age 14) comes trotting downstairs for some water 5 mins ago while agent Scully is masturbating an aubergine! Awks!
I managed to pause and navigate away but it is a pain. How do you watch grown up stuff when you have young teens?! They hang around and make it very tricky.
