You shouted at 7 PM. You said sorry at 10 PM. Here is the bedtime that helps both of you.
The time your child should be asleep, worked out from when they wake. Then the five steps I use to get there.

When does your child wake up?
Tap the time they usually wake. This is the time to be asleep, not the time to start getting ready.
No nap today? Aim for 6:30 PM.
No nap today? Aim for 7:00 PM.
No nap today? Aim for 7:30 PM.
No nap today? Aim for 8:00 PM.
No nap today? Aim for 8:30 PM.
How I worked it out. Sleep doctors (American Academy of Sleep Medicine, 2016) say a child needs 11 to 14 hours in a day at ages 1 to 2, and 10 to 13 hours at ages 3 to 5, naps included. A nap gives one to two of those hours. So the night has to give about 11. The subtraction is mine, not theirs. Every child differs by half an hour or so. If yours wakes happy, you have found it.
Count back one hour from that time. Start here.

Each step, and why it is there.
This is one father's plan, not a programme. It saves on this phone, so you can come back tomorrow.
0 of 5: Tick what you managed tonight.
A three-year-old is not three all day. In the morning they talk, share and wait. By evening, they act like one. This chart is my sketch as a dad, not a measurement.
I am Manjunath. I built a maze for my daughter, and these guides are what I learnt on the way.
A calm evening starts with asking less.
Of a small child, and of yourself. As an engineer I draw things to understand them. So I drew the evening.

The three-year-old you see all morning sits on top. Underneath, they are still mostly baby. When they are tired, the baby comes up. So at seven, don't explain. Hold them.
"Still majority baby underneath."
Those are the words of Nupur D Paiva, a clinical psychologist and child psychotherapist, speaking on Sitaara in August 2026. She says young children carry their earlier selves inside them. One moment they seem grown, and a little later they need what a much younger child needs. I only drew what she said.
One study agrees with the tired part. Researchers followed 91 children aged 3 to 5 for six months (Godzik and colleagues, Frontiers in Sleep, 2024). On the weeks a child slept worse than their own usual, their parents reported they handled their feelings worse. The effect was small, and the families were mostly well-off Americans. It matches what most parents describe at seven.
And you have been on duty since six in the morning. By seven, you have very little left as well. Nobody failed. It was just late.
Tap each one.
These are my answers as a father, not research findings.
7 PM. They are crying because you gave the red cup, not the blue one. Best first move?
Lap first, words later. It was never about the cup. And sitting down is less work for you than arguing with someone who is, for this hour, one year old.
The sorry said to a sleeping child helps only us. Say it at breakfast too. They will remember that you came back.
Hanuman's Fruit Hunt
The little Hanuman who thought the sun was a fruit, on a birch wood board. Your child guides every fruit along the path with a magnetic pen. It does nothing until their hand moves it. No batteries, no sound. For 15 months and up.
