We all make mistakes.
Especially in parenting.
When you make a mistake the best thing to do apologize. It's good for your kids to see that you are human and it's builds a relationship with your child. So many times I have had to say: "You know, you are right-I was WRONG." There is that word-wrong. Why is that so hard to say? Is it because we feel that if we admit that we are wrong it makes us less of a parent? Or that our kids will hold it against us? Whatever the reason-forget it, admit it, and move on!
