Whenever my daughter and I visit her lolo daddy and lola mommy, it is important to never forget to say good night. I take her and her cousin to their grandparents' room to give them a kiss and a hug before going to bed. It has become their practice since we practice it in my own home.
Those little things that seem trivial would be the thing they would remember growing up. If it has become the practice then it would become a habit. A habit would be hard to get rid off. And I wouldn't want them to forget to do it. I want them to do the same to me too.
