try and say that dad still loves mum ever so much but .... dad loves another less special mum and that they all love her lots and lots and will never stop loving her   good luck xx 

Just say that ur mummy and daddy have new ppl that they love- and these ppl are like new mummy and daddy but they arent as special as real mummy n daddy because they love you that little bit more. Kiwi

Tell her how her daddy loves some one else n mummy finds it hard because she wanted to be still loved by daddy. would this help or not?? Do u want to explain the situation slightly more?? i might be able to give you some more help, Kiwi
