Dr Karp recommends the "clap-growl" technique. "“When you see your young child doing something that you don’t like, rather than spanking them, you give a good sharp clap, which gets their attention, and then with a serious look on your face, you admonish them. ‘No bite!’ with that index finger extended. And then, do what’s called a double take; you look away from them for a second, and then you look back at them just a few seconds later with that stern look again and say, ‘No bite,’” he says.He explains that disciplining a child is like training a dog- it takes some time and some repeating. If you show who's boss from the beginning, the struggle will lessen.
