I've got 3 girls, oldest is 4, middle turns 3 in January, youngest is one. We've got another on the way, and boy am I ever hoping for that boy! Anyway, I'm old school. Neither my wife or I shy away from spankings or time out for either of our older girls (obviously not the one year old though). Our oldest is DEFINITELY pushing boundaries, and the 2-year old is kinda glomming onto it. However, whenever we go out we always get compliments on how well behaved our kids are. They can get out of hand at home, but they always do well when out and about / at church etc. I guess we would be considered "tough" parents, but I'm ok with that. I'd rather my girls know what consequences are and understand that if they push, they won't like the results. The real key is to balance the punishment/discipline with love. I love those girls to the end of days, and they know it. I'd do anything for them, including giving them a whooping for misbehaving. So far it seems to be working.
