Be wary of encouraging or allowing your significant other to discipline your children, as this can have a negative impact on the mental health of your children, as well as the intimacy of your relationship.
As a parent, you can start by telling your children: Watch for the response.
Many children will say, “I know, I know,” while secretly believing that they did, in fact, cause the divorce.
On the other hand, there are several factors that can increase stability for children and help them make transitions, including having two actively involved parents who tend to be monogamous with their significant others.
It helps, too, if those parents maintain a stable lifestyle in terms of employment, residential location, and health.
If you are the sole parent (your former partner is not involved or is minimally involved) wait at least a year and even then proceed with extreme caution.
