LOL - I don't have kids!
When I had my friends kids staying I heard myself saying the phrases that they used on me!
I do know that Nick hasn't been anywhere near as strict with his boys on a few things than Mum & Dad were with us. Tim doesn't have kids. but again moans about how strict they were in certain aspects. However I don't see that problem, and am glad I had definate guidelines to stick to. We were never smacked, but all knew when we had upset them.
