Child development calendar: 0–24 months
Month by month after the birth: growth, new skills, feeding, sleep, check-ups and the Uzbekistan vaccination calendar.
First year
Birth to 1 month
The first month: welcome to the world
Birth 2.5–4.3 kg; about 3.4–5.1 kg by one month · Birth 46–53 cm; about 51–57 cm by one month
Your newborn is adjusting to life outside the womb: eating often, sleeping in short stretches and learning your voice and smell. Most of what you do now – feeding, holding, talking – is exactly what your baby needs.
1 months
One month old: the first real smile
4.2–6.0 kg · 54–60 cm
Between one and two months your baby becomes more awake and more interested in you. Feeding is settling into a rhythm, the neck is getting stronger, and the first social smile is on its way.
2 months
Two months old: cooing and conversations
4.9–7.0 kg · 57–63 cm
At two months your baby smiles at you on purpose, answers with soft coos and holds the head more steadily. This is also the month of the first routine vaccinations at the polyclinic.
3 months
Three months old: laughter and lifting up
5.6–7.8 kg · 60–66 cm
Three-month-olds are sociable and busy: they laugh, grab at toys, hold the head up on the tummy and clearly know who their people are. The second round of vaccines is due this month.
4 months
Four months old: rolling and reaching
6.1–8.4 kg · 62–68 cm
At four months your baby holds the head steady, reaches out and grasps, may roll from tummy to back and babbles in long strings. The third round of vaccines is due at the polyclinic.
5 months
Five months old: sitting up and getting ready for solids
6.5–8.9 kg · 64–70 cm
Five-month-olds are on the move: rolling both ways, sitting with support, grabbing and passing toys, turning to their name. Breast milk is still the only food, but 6 months – and the first spoonfuls – is close.
6 months
Six months: first spoonfuls
6.9–9.4 kg · 65–71 cm
Half a birthday has passed. Many babies now sit with a little support, roll both ways and are ready for their first spoonfuls of food alongside breast milk or formula.
7 months
Seven months: sitting steady
7.2–9.8 kg · 67–73 cm
Many seven-month-olds sit without support, freeing both hands for exploring. Food is becoming more varied, and your baby is beginning to understand your tone of voice.
8 months
Eight months: on the move
7.5–10.2 kg · 68–75 cm
Many eight-month-olds start moving across the room by creeping, crawling or rolling, and some pull themselves up to stand. Stranger anxiety is a healthy sign of attachment, not bad manners.
9 months
Nine months: crawling and cruising
7.7–10.5 kg · 70–76 cm
Many nine-month-olds crawl well and cruise along furniture. They look for a toy that disappears under a blanket, point, and say "mama" and "dada" sounds. This month brings the IPV-2 polio vaccine and a check-up.
10 months
Ten months: standing tall
8.0–10.8 kg · 71–78 cm
Many ten-month-olds stand holding on to furniture, clap, and understand simple words like "give" and "bye-bye". Growth is slower, meals look more like family food, and the chatter is constant.
11 months
Eleven months: almost one
8.2–11.1 kg · 72–79 cm
Many eleven-month-olds take steps holding your hands, drink from a cup with help and say one or two words with meaning. This is the month to prepare for the one-year check-up and vaccines.
Second year
12–14 months
One year old: first steps and first words
8.5–11.8 kg · 74–82 cm
Around the first birthday many children stand alone, some walk, and almost all understand far more than they can say. Growth slows, appetite becomes uneven, and the one-year check-up and vaccines are due at the polyclinic.
15–17 months
Fifteen to seventeen months: a confident walker with opinions
9.0–12.6 kg · 77–85 cm
Most children now walk well and are busy exploring every corner of the home. Speech grows slowly from a few words while understanding races ahead, and frustration spills over as tantrums. DTP-4 and OPV-4 are due at 16 months.
18–20 months
Eighteen to twenty months: running, climbing and pretending
9.5–13.3 kg · 80–88 cm
Children at this age run, climb and want to do everything themselves. Vocabulary grows to 10–20 words or more and the first pretend games appear, such as feeding a doll. The 18-month check-up looks closely at speech, hearing and teeth.
21–23 months
Approaching two: two-word phrases and "no!"
10.0–14.0 kg · 82–91 cm
By the second birthday many children know 50 or more words and begin to put two together. They kick a ball, climb stairs holding a hand, sort shapes and insist on doing things themselves. The two-year review at the polyclinic looks at speech, growth and behaviour.
