why not "mama mea are..."?
It should be mama mea. It can easily be mistaken for The mother
In Romanian is this something you would say when speaking to a sibling or your father:
'Mom has a brother.'
or when talking with someone else:
'My mother has a brother'
In Spanish we say 'the mum/dad' referring to our parents as long as we all know that I'm talking about our parents.
When talking with other people, we say 'my mum/dad'.
