DS was like this for a while. I think they do go through stages, regardless of your family situation. DH was a stay at home parent from 2-7 months and has always spent a fair bit of time with DS when he is home.
For about 6 months, maybe starting at a similar age, DS would only have mummy. He too would scream at daddy to go away. Then things changed again. It's more balanced now, but daddy has to do bedtimes and sometimes it's me that gets screamed up.
