Author’s practical guidance
Another child lives in the other house
Source named in the book: long-term research on stepfamilies (Hetherington)
This is not the arrival of a sibling and it should not be handled like one.
Say this now
“He lives there. You live there too, on your days.”
Puts both children in the house, not one as a visitor.
“You don't have to like him. No hitting, no grabbing.”
A clear floor with no obligation above it.
Do this
- Ask for something that stays theirs in that house — a drawer, a shelf, a bed.
- Do not require affection or ask about it afterward.
- Let them complain to you without repeating it to the other house.
- Use "your days there", not "when you visit."
- Give it a year before expecting warmth.
Avoid this
- "You have a new brother now!" A relationship announced rather than grown.
- "You have to share, you're a guest." The word guest is the wound, not the sharing.
- Asking whether they played nicely. Requires a report on somebody else's child.
If it repeats
Friction over territory is usual for the first year and usually fades as the house becomes familiar. Persistent misery about going, tied specifically to the other child, is worth raising with the other parent directly.
Why the book suggests this
This is not the arrival of a sibling and it should not be handled like one. Long-term work on stepfamilies describes these relationships forming slowly, over years, and forming worse when they are announced. Your child has two days a week in a house where somebody else already lives.
That produces a specific problem, and it is about ownership rather than jealousy: the other child was there when they were not, knows where things are and does not have to leave on Sunday.
