How strict are you as a parent?

Of course we have boundaries set for our children if we didnt they would one run riot and two probably hurt themselves, mostly our boundaries are set in place to keep them safe, I dont think im that strict I accept that at times they will mis behave and we deal with it when it happens then cuddles and its forgotten about I wont have my children thinking im holding some sort of grudge against them for some little mistake. However there are three things I will not tolerate 1:being rude to me their dad anyone really, 2: Spitting 3: Biting, I will not tolerate any of those and they are punished with no exceptions generally they are polite and have only ever bitten once, spitting will happen im sure however I think they understand my feelings on it as my eldest saw a man do it in the street and loudly said oh mummy thats disgusting isnt it!!
