I heard about this book about 4 years ago, when we were having some issues with our oldest child Emma. She was acting out a lot, and not really acting like herself and we could not figure out why. A friend of mine told me about the book The 5 Love Languages of Children. I was pregnant with our third at the time, and had a lot of complications, and was very uncomfortable for the majority of the pregnancy, so I wasn't spending any snuggle time with her, we had very short hugs and kisses goodnight which was not how it was before I had gotten pregnant.
After reading the book I realized that her love language was physical touch, so the fact that I was no longer giving her that snuggle time and big hugs, was in turn, not showing her that I loved her, even though I was still telling her all the time. Needless to say I felt horrible, and once I figured it out, I made sure that I hugged her and kissed her and snuggled with her as much as possible. Within a week, her behavior went right back to normal because in my opinion, she didn't feel the need to act out anymore because she once again knew that I loved her.
I came across this website today where you can actually take a small test (takes about 5 minutes) to find out not only what your kids love languages are, but what yours and your spouses are.
Mine happens to be Words of Affirmation, meaning that when Bryan says nice things to me that makes me know that I love him. His is physical touch like Emma, so he can hug me 50 times a day thinking that I must know he loves me, but that doesn't mean as much to me as it does to him.
This is something that has really strengthened our marriage, and our parenting abilities, so I highly recommend going to the website and taking the test! Feel free to share your results too!
Oh, and if you don't have kids or a spouse? There is a test for singles too!
