I can get:
“The night daddy went to jail”
“Mama, Mummy and me”
“Dada, Daddy and me”
“Do I have a Daddy?” (Bit of a harsh title if you ask me, it’s about donor conception)
But I can’t find one bloody book about growing up without a dad around. I wouldn’t have thought it was a small market either 
Any suggestions?
Or we can write a MN one instead. All proceeds to go to strengthening data protection 
Working title....”mummy, where’s my daddy”
