But here on my relatives knocked... each other they are native sisters, one divorced (the husband's surname remained), the other unmarried, both have a child. Externally not like: one "in mom", the other "in dad". We bought an apartment one for two, as each would not pull themselves. The teacher in the kindergarten of the younger was warned that the child is coming to the mother, then "lola", decided that something is not clean here...
Nothing, passports showed, the presence of normal conditions for children showed - lag behind. What if there were "two mothers"?

I am also interested. What if it were?
Suppose that the lesbian surname was taken in common, and what would they be able to present?
So the story of the series "Of course incredible". It may end up happening, but the consequences, with the slightest planning of such, are minimal. The child is stressed.
And yes, the fact that your relatives are not a same-sex family, did not prevent the disgust that climbs everyone to bed and divides people by intimate preferences, add to the child of your relatives problems.
