Parents’ questions, short answers

Simple answers about screens, sleep, mood and focus. Habits only. If something worries you, talk to your pediatrician.

Screens

Why does my kid cry when the tablet turns off?

Games and short videos give fast, easy rewards. When they stop all at once, the brain protests, and that looks like tears or yelling. It does not mean your kid is bad. Warnings before the end help a lot. Our character Dopa explains it in this short read.

How do I end screen time without a fight?

Warn at 5 minutes and again at 1 minute. When time is up, have something small ready to do together, like setting the table or a quick game. Do it the same way every day, so your kid knows what comes next.

Should screens be off before bed?

We suggest turning screens off about one hour before bed, so the evening can slow down. Use that hour for the same calm steps every night: bath, book, lights out.

Sleep

How much sleep does my child need?

Sleep experts recommend 10 to 13 hours a day for kids aged 3 to 5 (naps count), 9 to 12 hours for ages 6 to 12, and 8 to 10 hours for teens aged 13 to 18. Source: AASM consensus, Journal of Clinical Sleep Medicine, 2016, endorsed by the American Academy of Pediatrics (checked 25 Oct 2026). If your child sleeps much less or much more, ask your pediatrician.

How can I help my child fall asleep without medicine?

Keep the same bedtime and wake-up time, even on weekends if you can. Get daylight in the morning. Make the last hour calm and screen-free, with the same steps every night. If sleep problems go on for weeks, talk to your pediatrician.

Mood and behavior

My kid gets angry fast. What can I try?

Stay calm and keep it short. Name the feeling, keep the limit and breathe slowly together: “You’re really mad. That’s okay. The answer is still no.” Check the basics too: sleep, meals and time outside. If anger happens a lot or someone gets hurt, talk to your pediatrician.

Why is my kid so grumpy after school?

Many kids hold it together all day and let it out at home. A snack and some moving before questions or homework can help them reset.

Focus and energy

How can I help my child focus on homework?

Cut the work into small parts with a clear finish line, so each part gives a small win. Put phones away and add a short movement break between parts.

My kid sits most of the day. How can we move more?

It does not need to be a sport. Anything fun that makes them out of breath counts: a 5-minute dance party, a race down the street, a game of tag.

Teens

How do I talk to my teen about phones and sleep?

Make a deal, not a rule. Agree together on a time when phones go to charge outside the bedroom. Teens are more likely to keep a deal they helped make.

Brain chemicals, in simple words

What is dopamine?

Dopamine is a brain chemical linked to wanting, trying and reward. In our cartoons it’s Dopa, who hands out gold stars when you finish something.

What is serotonin?

Serotonin is a brain chemical linked to mood and calm. In our cartoons it’s Sero, who likes bright mornings and days that look the same.

What is cortisol?

Cortisol is the body’s stress hormone. It helps in real danger. In our cartoons it’s Corti, an alarm clock that wears everyone out when it never stops ringing.
