You know that smacking your child is not okay? Now read this
About to blow your lid?
Smacking is rarely a planned, thought-out response. We lash out when we're seeing red - then feel dreadful afterwards. Plus, whilst it may stop a misbehaving child in his tracks, long-term it can make matters worse.
When a parent smacks, the child gets the message that this how to deal with anger, and may start hitting other kids. Even if he doesn't, it's more likely to lead to defiance rather than respect for you.
So, if you feel anger bubbling up, take a deep breath and remove yourself from the situation for a few moments. This acts as time out for grown-ups, and is often enough to avoid lashing out.
