Always tell them you love them no matter how old.
Hug them before let them enter the school gate. Hug them when they came back from school. Hug them when they feel sad, sick, unhappy. Hug them when they show you their bad results. Hug them when they show you their good results. Tell and show them that you love them no matters what. Hug them while you still given the opportunities to do that because they are yours! ~ Saya Solehah
Hug and kiss! Always tell them you love them. How much they mean to you. How beautiful and wonderful they are. Let them know they are special!
