The BIFF Method: Brief, Informative, Friendly, Firm
BIFF was developed for the moments when the conversation itself is the conflict — not the topic on the surface. Each letter is a constraint on a single message, and none of them are optional. Drop one and the message gives a high-conflict co-parent something to escalate from.
| Letter | Meaning & rule |
|---|---|
| B · Brief | Keep the message as short as you can while still being complete. Two sentences is usually the limit. If you cannot say it in two, you have added too much. |
| I · Informative | Every BIFF message communicates something concrete — a time, a location, a confirmed decision, an answer to a direct question. The goal is to be unambiguous. |
| F · Friendly | Friendly does not mean warm. It means greeting-level: a brief opener, no sarcasm, no condescension, no closing jab. The absence of any phrase that can be read as an attack. |
| F · Firm | One closing sentence that closes the loop — "Let me know if that works" or "I will plan on that." It states what is happening. It does not invite discussion. |
Three Sample Custody Schedules You Can Adapt
There is no single schedule that fits every family. Pick the rotation that matches the kids' ages, the distance between households, and how much change your co-parent can sustain without escalating. Each pattern below is shown as a 14-day window so a full two-week cycle is visible at a glance.
Alternating Weeks
| Wk | M | T | W | Th | F | Sa | Su |
|---|---|---|---|---|---|---|---|
| 1 | A | A | A | A | A | A | A |
| 2 | B | B | B | B | B | B | B |
Best for: older kids and teens who can hold a two-week rhythm, and households far enough apart that mid-week handoffs are impractical.
2-2-3 Rotation
| Wk | M | T | W | Th | F | Sa | Su |
|---|---|---|---|---|---|---|---|
| 1 | A | A | B | B | A | A | A |
| 2 | B | B | A | A | B | B | B |
Best for: younger kids who benefit from frequent contact with both parents, and households close enough for mid-week swaps to work.
Fixed Split + Alternating Weekends
| Wk | M | T | W | Th | F | Sa | Su |
|---|---|---|---|---|---|---|---|
| 1 | A | A | B | B | A | A | A |
| 2 | A | A | B | B | B | B | B |
Best for: school-age kids who need a predictable weekday routine, with weekend time split evenly so neither parent is locked out of weekends.
5 Text Scripts You Can Paste Verbatim
Each script below is fully BIFF-shaped — no more than four sentences, the facts on the line, no openings for a reactive reply. Replace bracketed details with your specifics and send as-is.
1 · Requesting a schedule swapScenario · week-of change, when you need the kids on a day that is normally the other parent's
Hi — I need to swap this Saturday for Sunday [date]. I can take the kids 9am–6pm that day. Let me know if that works for you.2 · Responding to criticism
Scenario · a message that lands as a personal dig, where engaging will only escalate
I hear that you're frustrated. I'd like to keep our texts focused on the kids' schedule and logistics so we can both stay on track.3 · Confirming a pickup
Scenario · pre-pickup, leaving no room for a "well, actually..." reply
I’ll be at pickup at [time]. Kids are packed, homework is done. Text me if anything changes on your end.4 · Declining a last-minute request
Scenario · an ask that arrives today for today, where a flat "no" invites a fight
That doesn’t work with this week’s schedule. Here’s what I can do instead: [specific alternative time or date]. Let me know.5 · Looping in the kids’ teacher
Scenario · one parent has new school-side information the other needs to act on
Hi — [Teacher name] flagged that [kid] needs [specific item or action] by [date]. I’ll handle it on my next day. Want me to loop the other parent in too?Save these and 50+ more in Tag Team Parenting →
6 Ground Rules for the Next Year
Hard rules you can write down and hold both parents to. Print this page and keep it where you draft messages — it is faster to follow a rule than to remember one in the heat of the moment.
- Keep messages about the kids. Logistics, schedule, school, health. Anything else goes to a different channel — or nowhere at all.
- Default to written, asynchronous text. Real-time chat invites reactive replies. A text sent at noon gets answered after a pause to think.
- Never draft a reply in the same minute you read the trigger message. Walk away for at least ten minutes. Most texts you would have sent in that minute are the ones you wish you hadn’t.
- Treat the record like a court exhibit. If it would look bad in front of a judge, do not type it. BIFF messages make the record work for you, not against you.
- Match the BIFF shape on hard topics. Brief, Informative, Friendly, Firm — every message, even when you are angry. Especially when you are angry.
- Re-read messages as if the other parent just woke up and has no context. If your text cannot survive that re-read, it is not finished — rewrite it until it can.
These six rules work alongside parallel parenting: the structured low-contact approach used when direct co-parenting has become unsafe or unsustainable. Under parallel parenting, communication is logged and limited, decisions are made independently on each side, and the only required contact is around the kids’ actual transitions.
