A cousin of mine has married his girlfriend of several years in an opposite sex marriage and she ahs brought to children into the marriage. Both of those children have different fathers but the two have been so young when their mother married my cousin that they can’t really recall living with their biological fathers. So my cousin’s stepchildren grew up calling him “Dad”. Ironically the children refer to their biological fathers as “uncles” which worked out fine – at least for my cousin, his wife and the two children.
The only potential problem that my cousin and his wife see coming up is that their daughter is not going to be seen by an “uncle” and they now need to look for a man who is willing to frequently take the child out to avoid jealousy.
And someone was really concerned about same-sex parents?
