Mothers have one of the most difficult jobs on the planet. Not only do they give birth to all of their children (which is a difficult process on its own), but they also do most of the child rearing. It's always mom who the children go to when they need help or a question answered. Mom is the first person on their mind, because as we all know, mother knows best.

Being a mother is never all that easy. Children have a habit of being little terrors one minute and sweet angels the next. On days when she feels like she's failed at motherhood, your wife needs to be reassured about how well she's doing at being a mother. Because she really is doing a good job.

Here are 17 ways you can assure your wife that she is an amazing mother:

1. "You deserve the absolute best."

2. "You are an inspiring role model for our children."

3. "You make a great difference in our children's lives."

4. "You have an innate ability to lead and inspire everyone, not only our children."

5. "Our children learn a lot from you."

6. "You always know the right thing to say."

7. "I appreciate you and everything you do for me and the kids."

8. "You are exactly what our child needs."

9. "I love coming home to you and the wonderful life you've built for our family."

10. "You're fulfilling the greatest calling in the universe."

11. "I love and admire you for how you are raising our children."

12. "You make everything absolutely beautiful."

13. "The difficulties you have are making you stronger."

14. "You sleep. I'll get up with the kids. You already do a wonderful job during the day!"

15. "You are the best mother you can be."

16. "Go have a day for yourself. I'll stay home, clean the house and take care of the kids."

17. "The greatest gift is having you as my wife and the mother of our children"

Your wife means more to you than anything in the world. As a mother, she is at the center of her children's lives. Reminding her how great she is at being a mother will help her pick herself back up and be happier on the hardest days.
