I am always disappointed by the Mother's Day song in the children's song book.  I won't explain all the reasons why but if you are in the same position I have a solution for you.  I love the upbeat music and style of Daddy's Homecoming so I asked a friend to write lyrics for a Mother's Day song using that music.  This is what she came up with. (Thank you Emily!!)
We added actions, I let the kids help me come up with them.  For the first phrase we did hands shaped like a heart.
