That’s the best thing about being a mother. You are never alone. You are now not one but two-in-one. You think of somebody else before your own self. Your needs take a back seat. You know now somebody depends on you. Even when your children are grown up, you will be the only one always wishing the very best for them, even when they do not know or acknowledge.
By the way, who does all these things for us? Only God who runs the universe.
That means, every mother (in fact fathers too) run the universe, by bringing children into the world and then bringing up their children unconditionally.
Be a proud mother and always be proud of your mother. Say thank you whenever you can!
