I have 2 boys, 1 will be 2.5 in January and 1 is 10 months. The oldest one says some CRAZY stuff but we don't cuss or watch stuff with cusswords in it so he's been cool on that but I took him to a homeboys house for the super bowl when he was like a year and a half and he was bustin out all kinds of cusswords there for a couple months. It's kinda hard to discipline a kid that age for saying it cause they really don't understand. We spank my son for some stuff but you have to be calm when you discipline them or they associate punishment with being mad. So when he'd get mad, he'd hit my youngest son or hit me and his mom.
Before he was 2, I was wearing a bruce lee shirt and I thought he was asleep in his crib. I walked in to check on him and leaned over and he said "BRUCE LEE WAAAAAAAAAAAAAH" like bruce did and hit me in the eye. I was dying laughing from that crap
