Stay united...

One of the most important things we can do for our children is provide a united front. Children are masters at dividing and conquering to get what they want. 

Make it a goal to always stand with your wife in any decisions made. Your children need to know what mom says, goes, and you support her 100%.  Your wife needs to know you always have her back. 

If there are things you do not agree with, then talk about them privately and come up with a plan you both agree to.
