You asked a simple question on Tuesday, and it's Thursday. You've reread your own message twice, wondering if you worded it wrong, or if you should ask again.
There's no single rule that fits every family, but there is a way to think about the wait that takes some of the guesswork out of it.
There's no official waiting period
No court, solicitor or app sets a deadline for replying to a co-parenting message. If a court order or parenting plan in your case does set out how and when you communicate, that comes first, before anything in this article.
Short of that, it's down to the two of you, and it usually settles into a pattern long before either of you ever talks about it out loud.
What a reasonable gap actually looks like
For the small, logistical stuff, a swap, a kit bag, what time to collect, same day or next day is typical for most co-parenting pairs. For anything that needs real thought, a school choice, a holiday request, a bigger cost, a few days isn't unusual and isn't a red flag on its own.
The useful measure isn't a fixed number of hours. It's whether the pattern is consistent. A co-parent who takes two days on everything isn't being difficult, that may just be their pace. A co-parent who replies within the hour on easy questions and goes quiet only on the ones they'd rather not answer is telling you something different.
Why the waiting feels worse than it is
An unanswered question has a way of taking up more room in your head than its size should allow. You can't fully plan the weekend, book the appointment or answer your own child until it lands, so you end up carrying it around instead of just waiting for it.
That's not you being impatient. It's what happens when one open question sits between two households instead of inside one.
When, and how, to follow up
One plain follow-up is reasonable. Repeat the original question in a line or two, and give a date you need the answer by if there is one: 'Just following up on Saturday's collection time, need to know by Thursday.'
Sending the same question three times in a day rarely speeds things up, and it tends to read as pressure rather than urgency. If the first message was clear, a second clear one is usually enough. After that, it's worth deciding for yourself what the default is if no answer comes, rather than leaving it open indefinitely.
When the silence is something else
Occasional slow replies are just life. A pattern of going quiet specifically on the questions that matter, the ones about money, access or a decision your co-parent would rather avoid, is a different problem, and it's worth naming to yourself as that rather than putting it down to a busy week every time.
If that's where you are, our piece on co-parenting when the other parent won't communicate goes into parallel parenting and what to do when the silence is the pattern, not the exception.
Keep the question and the answer in one place
Part of what makes the wait feel worse is not having anywhere to put the question once you've asked it. In ParenThing, your messages stay exactly as written alongside your shared calendar, costs and plans, so the question, the date and whatever reply follows are all sitting in the same place rather than scattered across texts and screenshots.
Every message is checked for tone before it sends, on both sides, which takes some of the heat out of a follow-up written on a bad day. There's a free version if you want to see how it fits your family.
Common questions
Is there a legal requirement for a co-parent to reply within a certain time?
No. There's no court-set deadline for replying to a co-parenting message in Ireland or the UK. If a court order or parenting plan for your family sets out communication rules, follow that first.
What counts as a reasonable response time for co-parenting messages?
Most families settle into same-day or next-day replies for day-to-day logistics, and a little longer for anything that needs real thought. The useful measure isn't a fixed number of hours, it's whether the pattern between you is consistent.
Should I follow up if I haven't heard back?
One plain, specific follow-up is reasonable, for example repeating the original question with a date you need an answer by. Sending it again the same day rarely speeds things up and can read as pressure.
