Step family not part of the wedding party
My son is getting married soon and my wife is his stepmother. The bride to be has manipulated "her way" with the wedding party and has left out all of the step family siblings (our other children, 4 and 5 years old). My son seems to be oblivious to all that is going on. He says he didnt think about his little step brother and step sister untill it was brough to his attnetion. However the bride to be knew this was an issue already. My wife (his stepmother) has now lost her temper with the bride to be wanting to know why our children (the step family) have been excluded from the wedding party. What is correct wedding etiquette in this situation? Normally all children close to the bride and groom would be invited to attend. There is plenty for 3 or 4 little children to do in a wedding.
