My fella is only 15 months but these are the values which are important to my husband and I.
The things I'd be very strict on are education and manners. They will go to school unless they're genuinely sick. There won't be any duvet week days in our home.
They will be taught to be mannerly and respectful. We, as parents, will be respectful of them in return and we'd teach them to respect themselves too.
I don't want my kids swearing like fishwives. I'm sure they'll do it with their peers but I'd like to think they'd be articulate enough to be able to form sentences without strings of expletives. There's a time and place for cursing but it's awful to hear people (young and old) constantly cursing when they speak.
