You won’t be able to enforce your expectations until your child is older, but the process will likely become one of the most enduring rules in parenting over time. One of your jobs as a dad is to protect and train your child, and even if it never really seems like it, kids crave structure. As your baby grows old enough to understand “yes” and “no,” make sure those words have meaning. Let your “yes” be yes and your “no” be no. Let your “I will” become “I did.” You’re not perfect, but now you’ve got a little adult watching you to see if the rules even matter.
