We have mentioned it a few times when it comes up - all families are different these days so it's just another mix like some families don't have a dad or a mum for one reason or another. And yes there are quite a few books out there that we have seen that have two mums or two dads in a same sex relationship at the library. One of my cousins is also in a same sex relationship with 2 daughters so I guess our family has some background there - but it's also a downside as the other members of the family are quite stupid about it.

I think these days it is less of a stigma than say 10 years ago but you're right in that there will probably be issues that arise more in middle primary - younger kids are a lot more accepting ofthe situation so if DD stays at the same school she may never get that reaction.
