The love of a grandmother for her grandchildren is not the same as the one of a mother, but somehow, it is also great and wonderful. The grandma loves her grandkids with a special blooding-bonding love.
She thinks a lot and takes care of her grandkids every time. On one hand, she understands that her grandkids are now on the way of growing up exactly like what her children have passed through. And that adventure has been witnessed by her, and she can feel and understand how hard it is for her kids to grow up.
On the other hand, it is because of the love for her children. They are parents now, and they are worried about their own kids. The grandma knows that, and because she loves her children, she also loves their kids.
And although her grandkids are not always beside her, they still have a special place in her heart. When she had kids, her heart was filled with love for them, and when she had grandkids, her heart was even broadened for all of them.
