Today was DD's 4th birthday. She hasn't had any contact with her father since May 2008, mainly his choice, though I haven't attempted to initiate contact during this time either. He is a difficult man with a ferocious temper, we split up when DD was a baby (we were never married) and he wandered in and out of her life, sometimes seeing her every other day, sometimes not seeing her for months at a time. We had an almighty row in May last year, he was very abusive and said some awful things about DD, including that he never wanted to see her again, didn't want to be a father etc. I changed my numbers and he hasn't contacted us since (he knows my address - we live about 10 minutes away from each other.)
DD and I have carried on with our lives, she doesn't appear to have been affected by any of this. We still see exMIL regularly, she and I aren't exactly close but we get on ok and she and DD adore each other. She always visits us at our house, I will not let DD go to her house because exP is living there.
So, that's the background. Back to today, exMIL came round to visit DD and give her her birthday presents and cards. She also gave DD a card and present from exP, she did quietly mention to DD that they were from Daddy but DD was too engrossed in the present opening and didn't pay any attention, so I let her get on with it and haven't mentioned it again since. I'm now wondering if I've done the right thing. Should I have tried harder to explain to DD that these things were from her father?
Last year she didn't get any cards or presents from him for birthday or christmas so it's not something I've had to deal with before. Should I mention it to her tomorrow or just leave it? She has asked me if she has a daddy before and I've told her that she does, we just don't see him very much. She's always been happy with this reply and never asked any further questions.
