Care arrangements

Care arrangements explained

An overview of the most common models — alternating weeks, 3-4-4-3, 2-2-5-5, and others. What works for different age groups?

Choosing a care schedule that fits

Why the fit between a rotation and a family's circumstances — the distance between homes, each parent's working week, the child's age — matters more than the name of the pattern, and how to choose one that holds.

What a care schedule distributes

Why the name of an arrangement hides what it actually distributes — the weekends, school nights and handovers each home ends up with, and how to read the pattern before agreeing to it.

Shared residence vs. primary residence — what is the difference?

What it means in practice for everyday life, decision-making, and the child's rights.

Why the words for shared care change at every border

Custody, residence, Wechselmodell, primary residential parent: separated families meet a different vocabulary in every country for the same arrangement.

Travel consent letters for children of separated parents

France, Germany and the UK require different paperwork, triggered differently, when a child crosses a border with one parent.

Birdnesting — when the child stays and the parents move

The arrangement where the child stays in one home and the parents rotate in and out — why it suits the months right after a separation, what it costs, and why it is usually a stage rather than a settled pattern.

Sharing holidays and school breaks

Common ways separated parents divide school breaks and the long summer, plus why agreeing dates early prevents most conflict.

How to keep two homes aligned with school — contacts, parent-teacher meetings, homework, sick days, and what to do when a child is struggling.

Medical and school decisions across two homes

Which decisions about a child's health and schooling need both parents' agreement, which do not, and what happens when parents disagree.

Starting kindergarten or school across two homes

What research says about the start of kindergarten and school, and how parents in two homes can share information, drop-offs and goodbyes.

Christmas across two homes

How co-parents split Christmas Eve and Day, when to agree the plan, gifts and traditions in two homes, and what to do when you cannot agree.

Gifts across two homes

Why gift-giving becomes a comparison point at Christmas, what research says about children and materialism, and how co-parents agree a budget without competing.
