Before I start by smacking I obviously mean a light smack on hand or bottom not anything that will cause any real pain.
Inlaws have horrendously behaved 2 and 4 year olds who've caused carnage whilst staying at ours all weekend. Inlaws have been using "the naughty step" which predictably (to me anyway) had no effect. I always raised ours with 3 strikes 1. a firm warning 2. shouting 3. a smack.
Inlaws were shocked when I told them this . I'm sure this was fairly normal when I was a child have attitudes changed ?
