I think it's a song Maa o Maa, I would like to dedicate it to my mother

Some good poems for Mother's Day are, A Mother's Love by Helen Steiner Rice, Mother o' Mine by Rudyard Kipling, and To My Mother by Edgar Allan Poe.

There never was a fonder smile than mother’s smile, no softer touch than mother’s touch. So sleep awhile and know she loves you more than “much.” So more than “much,” much more than “all.” Though tender words, these do not speak of love at all, nor how we fall and mother’s there, nor how we reach from nightmares in the ticking night and she is there to hold us tight. There never was a stronger back than father’s back, that held our weight and lifted us, when we were small, and bore us till we reached the gate, then held our hands that first bright mile till we could run, and did, then flew. But, oh, a mother’s tender smile will leap and follow after you!
