A recording is a different thing, not a lesser one
It is available at three in the morning. Children wake at three in the morning, and at that hour nobody is answering a video call. The recording is right there and it does not need anyone else to be awake. It works with no reception. There is no signal for long stretches of the drive out west, none in parts of the ranges, none in the middle of a flight. A file already on the device plays anyway. It can be played eleven times in a row. No adult alive reads the same book eleven times in a row at bedtime, and a four year old will ask. The recording does not sigh. And nobody is watching the child while it plays. On a call they can see their own face up on the screen, and some kids hold themselves a bit carefully because of it. With a recording they can lie on the floor, wander off, come back, say nothing at all.
Read it slower than feels natural, and leave the gaps in
Whatever pace feels right in your head is too fast. Try this. Read the first page the way you normally would, then read it again at a pace that feels faintly ridiculous. The ridiculous one is about right. Aim for roughly two breaths per page. When you finish a page, stop and count three in your head before you start the next one. Three seconds feels enormous when you are the one talking, and it is nothing at all to the person listening, who is turning a page or looking at the picture or drifting off. Do not fill the gap with instructions. Say "turn the page when you hear me stop" once at the beginning and then never again. If you are reading a paper book, leave the sound of the paper in. It is a cue, and it is also just a good sound.
Say their name at the start, and keep the last line evergreen
Open with about ten seconds of nothing clever. "Hello Ruby, it's Dad. This is the one with the bin truck. Get comfy." Their name, your name, the book. The end matters more than people expect, because the end is the part that plays when they are nearly asleep. Two rules for it. Anything dated goes at the front, not the back, so "I'm on days until Friday" belongs in the first ten seconds. Keep the final line evergreen, because this recording will get played again in March by a kid who has decided it is the good one. "That's the end, Ruby. I love you. Night." will still be true in March.
Do the silly voice you actually do
If you do a growly voice for the bear, do the growly voice. If you always say "oh no" on the same page, say it. If there is a joke you make on page four every single time, make the joke on page four. Most kids are not after a performance. They are after the specific set of noises you make when you read that particular book, and a flattened, polite version of you is more noticeable than a daft one. You will feel like an idiot, alone in the kitchen, talking to a phone. Everybody does.

One take, and leave the mistakes in
The urge is to re-record it until it is clean. Do not. What you would be sanding off is the part that makes it yours. Losing your place and saying "hang on, sorry, wrong page". The kettle clicking off. The dog. A magpie going berserk outside in September. You yawning at the end of a long day and not bothering to hide it. A perfect take sounds like an audiobook, and audiobooks are easy to come by. There is only one of the other thing. One take, unless the phone did not actually record.
Everyone hates their own recorded voice
When you talk, you hear yourself two ways at once. Some of the sound reaches your ears through the air, and some of it travels through the bones of your head, which carry the lower frequencies. A recording only picks up the air part. So your voice comes back thinner and higher than the one you have listened to your whole life, and it sounds wrong to you. Your child has never heard the bone version. What is on the file is the voice they already know from every voice message you have ever sent. Do not listen back with a critical ear. Just hand it over. For what it is worth, reading aloud without being any good at it is close to a national pastime. The Australian Library and Information Association reported 2,204,658 registered participants across 16,632 locations for National Simultaneous Storytime in 2025, and almost none of those readers were professionals.
Where to keep it, and when to make them
The plainest version works fine. The voice memo app on your phone, a paper book at your end, the same book at their end, and the file sent across. A second copy of a picture book is a small price for that to work. If you would rather the recording lived with the book instead of buried in a chat thread, that is what our app does. StoryLink is free for this part: you read one of the 333 books in the library, the recording saves against that book, and the child can play it back at their end whenever they want it. One note on timing. Recordings work best made in a batch, ahead of the nights that are already spoken for, rather than scrambled together at nine at night. Sit down with the roster or the changeover calendar for the next fortnight, count the nights, and make one book per night. Three on a Sunday afternoon covers most of a week. Start with the book they ask for most. That is the one that gets played.
