Absolutely!! When my daughter was in the house I told her every single day, multiple times a day. She was an only child. I adored her! I also hugged her every day. Now that she has moved out I still tell her every time I see her. And we also still hug every time.
There is something I have said to my daughter for many, many years every time she leaves. I'll say " I love you. Be careful." And she will always say " I will, I promise. I love you too, mom!"
I love hearing it. Its kind of our "ritual"
