Need help with a song

Hello everyone,

I am hoping someone here can help me out.

My brother is getting married next month and is hoping to do a mother - son dance with mom.

Does anyone know a slow song in Portuguese (of course) that is about a mother and child or mother and son?

Unfortunately my Brazilian music collection consists of one CD (mi perdoa vovo) and asking mom would spoil the surprise.

Any help would be greatly appreciated

Thanks
Carol
