Oh wow. This is screwed up. Did you and your husband get together after the children were dating? Or did the children get together after you and your husband did?





Honestly.. I would just be up front with him. Remind him that real brother and sisters do not get married, and that his brother and sister and not real brother and sisters since they have different moms and dads. I would suggest not having him attend the wedding. If he just hears it, it will go in one ear and out the other and he will grow up with this situation and get used to it. It may scar him to see his brother and sister kiss and have a full on wedding.How do i explain step siblings getting married to a 4 year old?
Simply tell her that they are not really brother and sister. They do not have the same mother and father. Remember...do not offer this information if she is not asking you for an explanation. Children will ask questions when they are confused. If she's not concerned or confused about this, don't explain it. She will figure this all out when she is much older and able to understand it.
