Can a persons LL change over months or years? Good question! Well, think about what you need and if that changes over time, depending on what you're going through in life. I've been a little confused on this myself because I know I need all the LL to be totally happy. I think maybe the book helps to zero in on the ones that are most important. And then maybe after they are met and someone feels loved at that level, the rest is the icing on the cake. I don't think it hurts to cover all of them, I think when it becomes a problem is when we're loving someone with our LL and thinking we're doing great, but they need us to love them in their LL more. It's like my H running around here cleaning because when I do things to serve him he feels loved. I think it's sweet, but if he wants to show me he loves me, he needs to focus more on physical displays of love and communication. Then there are days (like today) when going to the grocery store and dragging all the kids with him (and the only reason is so I can be quiet and restful) speaks HUGE as far as love goes.
And, I have to say that I've noticed in your posts that you get a good reaction out of your H by positive verbal reinforcement.
