What is the difference between a 'brother' and 'half brother'?
I know plenty of women that have children by different Fathers, the kids are not referrred to as 'half'. But this seems to be the case if a Father has children with more than one woman.
Technically you are a half sibling if you share only one parent. But I know plenty of people who don't like the half bit and refer to their half siblings as brother or sister.
My two daughters and one son have different dads, they don't refer to themselves as half siblings (neither do I), but in actual terms they are half siblings.
I have 6 full siblings from my mum and dad's marriage and two half brothers from my dad's second marriage.
Agreed with what's already been said - half sibling = one common parent.
I've got 3 sisters ..... technically speaking, I've got 2 half-sisters and one sister, as my 2 olders sisters have a different dad, but we ALWAYS refer to each other as brother and sister, NEVER as half brother/sister.
Similarly, i can't be doing with the 'half' nonsense, or 'step' either.
We have three daughters.
My wife had two of them with her first husband, and we had the thrd together, but they are all my daughters, and they all refer to each other as sisters - and I would take issue with anyone who said different.
When my wife and first married, there was the usual "You'l be wanting 'one of your own' now won't you?" to which i used to reply, "What do your think our daughters are - house guests?"
