My partner has a child who is almost 3 years old, the mother was a one night stand, he has had a dna test to prove paternity of the child!

We think she is being abused, I see her last week and she had a black eye and bruised cheek (i have a photo of this) i asked her what happened, all she said was ''mummy didnt do it'' to me that raises concern, it almost seemed like she had been told to say that?

When ever we see her she is in dirty clothes and a filthy nappy! her mother is a very aggressive person, she calls my partner up and demands things from him, ie Money and says if he dont give her money he cant see his child! My partner gives her £80 per week (twice what the CSA have asked him to pay) plus he buys clothes, nappys on top of that, he is a very good father! The mother takes the child to her heroine & crack addicts dads house, where there is drugs tool all over the place! When the child was born she was place on the protection list because of this and also because the mothers uncle is on the sex register
