When you are a single parent, but your situation is different to most because of choosing down the route of being a single parent due to fertility treatment with donated sperm.
Obviously, you are honest with the children themselves about this but just the same it's not necessarily something everyone needs to know about you or them.
I suppose I'm wondering how to handle the inevitable comments and questions and assumptions - 'do they see much of their dad, how old were they when you split?' and things that crop up at school relating to family trees, Father's Day, healthcare professionals, and so on.
I mostly try to go for deflection which works with questions but not with schools and so on!
Any advice? :)
