Part of her counseling covers the impact that children have on a marriage. Few have time, but people with successful marriages and families make the time. And the payoffs of a solid relationship are well worth the effort. The benefits to everyone in the family are well worth it. It makes difficult issues, like disciplining, easier to deal with, even if you don't always see eye to eye.
Kids are so perceptive, they'll take any opportunity to play one parent against another.
But when you feel close to your spouse, you're less likely to disagree with him in front of the kids. Close couples present a united front to their children. Even though they may have different discipline styles, they support each other's decisions and don't question them in front of the children. Children feel more secure, because they know what to expect. Parenting is easier because you and your spouse are united.
