...because my relatives are visiting and their kids can't keep off my ornaments/bookshelf/electricals etc?
Why do they think i want them to visit if i am going to be constantly rescuing my things from their child? Shouldn't they be doing the running around (at least some of the time), or have taught them by 18 months not to grab everything in sight; and by three years, shouldn't they know NOT to bash electronic equipent on the floor/throw items towards the telly?
