By age and stage

Pregnancy Pregnancy

Pregnancy is roughly 40 weeks of growth for both mother and baby. Regular checkups, folic acid, and avoiding harmful things are the foundation.

0–1 mo Newborn (0–1 month)

The first month is when baby and parents get used to each other. Good feeding, safe sleep, and spotting warning signs early are really what matters most.

1–3 mo 1–3 months

This is when babies start to look into your eyes and smile back. It is also the time of the most crying, so learning how to get through it together matters.

4–6 mo 4–6 months

Babies roll, reach and grab, and laugh out loud. Get ready to start solids around 6 months, and check safety again as they move more.

7–9 mo 7–9 months

Babies sit on their own, crawl, and become wary of strangers. As they explore, hazards at home multiply quickly, so safety checks matter most.

10–12 mo 10–12 months (around the first birthday)

Babies pull up, cruise along furniture, and may take first steps and say first words. Around the first birthday, both food and vaccines change a lot.

13–18 mo 13–18 months

As toddlers start walking, there is more they want to do and more they are not allowed to do. Help them express feelings with words and gestures, and let them explore freely within safe limits.

19–24 mo 19–24 months

Words and willpower grow together. Many toddlers start joining two words, and 'I do it!' becomes common. The checkup around the second birthday is a good time to review development.

Age 2–3 Ages 2–3

Children begin speaking in sentences and playing pretend. They leave diapers behind, learn to get along with peers, and ask 'Why?' constantly.

Age 4–5 Ages 4–5

Children make up stories and start rule-based games with friends. Before elementary school, it's time for booster shots and the last infant checkups.

Age 6–7 Ages 6–7 (starting elementary school)

A big transition from kindergarten to school. Managing on their own and getting used to the school rhythm matter more than letters and numbers.

Age 8–10 Ages 8–10 (middle elementary)

Independence and the weight of friendships grow. Some children begin showing the first signs of puberty. It's also a good time to set rules for a first smartphone.

Age 11–12 Ages 11–12 (upper elementary)

Children enter the heart of puberty, with fast changes in body and mind. They want independence but still need their parents' support.

Health & safety

Korea's Childhood Vaccine Schedule

In Korea, national vaccines are free at public health centers and designated clinics. Plan ahead using the standard schedule, and check exact dates and your child's record on the KDCA Immunization Helper.

Infant and Child Health Checkups

In Korea, infant and child health checkups are national screenings paid for by the National Health Insurance Service (NHIS). Each round has a fixed window, so check the dates and book ahead.

When Your Child Has a Fever

Fever is a sign the body is fighting infection, and how your child is doing matters more than the number. The exception: a baby under 3 months with 38°C or higher needs a doctor right away, however well they seem.

Handling Emergencies

If you feel it is an emergency, call 119 (Korea's emergency number) first without hesitation; the dispatcher will guide you through first aid by phone. This page is for education and does not replace hands-on CPR training.

Common Childhood Infections

Young children's immune systems are still developing, so several colds a year are normal. Most get better on their own, but don't miss the signs of dehydration or breathing trouble.

Teeth and Oral Care

Brushing starts the day the first tooth appears. A rice-grain smear of fluoride toothpaste, no bottle in bed, and a first dental visit around the first birthday are the basics of cavity prevention.

Home, Water and Outdoor Safety

Most childhood injuries happen at home, in the moment a caregiver looks away. Look around your home from your child's eye level and stay one step ahead of each stage.

Car Seats and Vehicle Safety

A car seat is needed from your child's very first ride. Don't rush to the next stage; using each seat until its height and weight limits is the safest choice.

Eczema, Food Allergy and Hives

Daily moisturizing is the foundation of eczema care, and food allergies are confirmed with a doctor rather than by test numbers alone. If your child struggles to breathe or goes limp, call 119 right away.

Children's Eye Health and Vision

Vision develops in early childhood, and amblyopia and strabismus respond best when found early. Keep up with vision checks at screenings and make time to play outdoors every day.

Feeding, sleep & everyday care

Breastfeeding

Breastfeeding is not a skill that works perfectly from day one; it is something parent and baby learn together. Getting help early, instead of struggling alone, is the biggest key.

Formula feeding

The core of formula feeding is to prepare it exactly as directed, handle it hygienically, and feed by your baby's cues. Formula-fed babies can be raised with just as much closeness and connection.

Starting solids and toddler food

Solid food fills nutritional gaps and is also how babies learn new tastes, textures and how to feed themselves. Follow your baby's readiness and pace rather than a fixed chart.

Sleep and safe sleep

With baby sleep, how safely comes before how long. Set up a safe sleep space first, then support sleep with age-appropriate expectations and a steady routine.

Toilet training

Toilet training goes faster and easier when a child is physically and emotionally ready. Praise and patience work better than pressure and scolding.

Media and screen time

The younger the child, the more they need human interaction, active play and sleep rather than screens. Instead of banning screens perfectly, aim for age-appropriate limits and family rules so media is used well and in moderation.

Discipline and emotion coaching

The goal of discipline is to help children build the ability to manage their own behavior. With clear, consistent limits on a foundation of warmth, children learn without being hit or frightened.

Developmental checks and delays

Every child develops at their own pace, but when you are worried about a delay, checking is better than waiting. Finding out early and helping early does the most for your child.

Children's Nutrition and Eating Habits

Regular meals from many food groups matter more than any special food. Parents decide what and when to serve; children decide how much to eat.

Reading and Play

Children's language and thinking grow through back-and-forth talk and play, not expensive learning toys. Read together a little every day and let your child lead the play.

Parents, family & support

Postpartum Recovery and Postpartum Depression

The weeks and months after birth are a time when body and mind recover together. Struggling is not a sign of weakness, and asking for help is also something you do for your baby.

Dads and Shared Parenting

A dad is not a "helper" but a parent raising the child together. The care skills you build in the first few weeks shape how parenting is shared for years.

Pregnancy, Birth, and Childcare Support Programs

In Korea, birth and childcare support runs from pregnancy through childhood. Most benefits must be applied for, so it matters to know what each program is and not miss the window.

Daycare, Kindergarten, and Childcare

Where to place your child depends on their age, your work hours, and your child's temperament. There is no single right answer; the key is choosing what fits your family and easing in slowly.

Raising siblings

Jealousy and fighting between siblings are normal. A parent's job is not to stop every fight but to help each child feel they have their own place, and to teach them how to work out conflict.

Allowance and money lessons

The aim of money education is not to save a lot, but to understand that money is limited and to build the ability to choose and wait. Spending small amounts and making mistakes is the best lesson.

Talking about puberty

Talking about puberty is not a single "sex ed talk" but short, frequent conversations that begin before the body changes. Accurate information and the trust that they can ask anything protect children best.

School violence and bullying

Bullying is not something a child can solve alone. Notice the signs early, listen calmly on your child's side, keep records and work with the school. That is the order that protects your child.
