At 12 months, your baby may pull to stand, move along furniture, wave, pick up small pieces with two fingers and use a familiar name for you. Another healthy baby may follow a different path. The first birthday is not an overnight deadline for walking, talking, stopping breastfeeding or giving up bottles. This UK guide explains the broad range around age 1, the NHS review and current vaccination schedule, and when to seek help.

01

What might a 12-month-old baby do?

The US Centers for Disease Control and Prevention (CDC) 1-year list includes waving, using a special name for a parent, understanding “no”, playing a simple turn-taking game, putting an object in a container, finding a hidden object, pulling to stand, cruising and picking up a small piece between finger and thumb. These are skills most children show by 1 year, not a diagnostic test or a checklist to complete on a birthday.

Look at progress across movement, communication, play and hand use. Contact your health visitor or GP promptly if your baby loses a skill, consistently uses one side less, becomes less responsive to sound or interaction, or if your concern persists. Corrected age may be considered for a baby born early.

02

Is it normal not to walk at 12 months?

In the World Health Organization (WHO) multicountry study, supported walking began from about 6 months to 13 months 3 weeks and independent walking from about 8 months 1 week to 17 months 3 weeks. These are broad observation windows, not targets. Not walking independently at 12 months, by itself, does not mean a delay.

Offer safe floor space and sturdy furniture; do not pull your baby upright by the arms or use a baby walker. Speak to your health visitor or GP without delay for loss of a skill, inability to sit independently, marked difficulty taking weight through both legs, persistent stiffness, floppiness or one-sided movement.

03

Meals and milk at 12 months

WHO guidance for ages 9–23 months uses 3–4 meals with 1–2 nutritious snacks as needed. This is not a demand to finish a fixed portion. Offer varied family foods in manageable textures, respond to hunger and fullness cues, and stop when your child turns away, closes the mouth or loses interest.

Breastfeeding can continue for as long as you both wish. From 12 months, the NHS allows pasteurised whole cow's milk as a main drink; infant formula is generally no longer needed unless a health professional advises otherwise. Discuss the change with your health visitor, GP or dietitian when there is allergy, restricted eating, growth concern, prematurity or another medical issue. Do not replace a varied diet with large amounts of milk.

04

Bottles, cups, honey and choking prevention

Turning 1 does not mean every bottle must disappear that day. Keep offering water or milk in an open cup or free-flow cup with meals and move away from bottles gradually. Speak to the health visitor or dentist about night bottles or tooth care. Honey is avoided before 12 months because of infant botulism; after 1, it still counts as free sugar and is not needed routinely.

Sit your child upright and stable with an attentive adult. Quarter grapes and cherry tomatoes lengthways and soften hard foods. Whole nuts, popcorn, round sausage slices and spoonfuls of thick nut butter can block the airway. If your child cannot breathe, cry or make a sound, or turns blue or grey, call 999 immediately. Learn paediatric choking first aid in a practical course.

05

First words, gestures and shared play

Your baby may wave, understand “no”, use a special name for you, copy sounds and take turns in a simple game. The order varies. Pointing to request something appears on CDC's 15-month list, so it should not be treated as a fixed 12-month deadline. One missing word or gesture is not a diagnosis.

Name what your baby sees, answer sounds with real words, share picture books and play turn-taking games. WHO does not recommend sedentary screen time at age 1; screens should not replace face-to-face talk, movement or sleep. Contact your health visitor or GP promptly if sounds or gestures are lost, interaction clearly reduces or response to sound is consistently absent.

06

How much should a 12-month-old sleep?

WHO recommends 11–14 hours of sleep in 24 hours, including naps, from age 1 to 2 years. The earlier infant range does not need to change abruptly on the birthday. Look at patterns across weeks, daytime behaviour and growth rather than scoring one day.

There is no official nap count, fixed wake-window schedule or requirement to sleep through for every 1-year-old. Movement, separation, teething, illness and routine changes may disrupt sleep temporarily. “12-month sleep regression” is not a diagnosis with a fixed start or length. Call 999 for severe breathing difficulty, blue or grey colour, or extreme difficulty waking; discuss pauses in breathing or persistent loud snoring with the GP.

07

The NHS 9–12 month review and one-year vaccinations

The NHS offers a health and development review between 9 and 12 months, usually with a health visitor. It covers areas such as development, growth, feeding, behaviour and safety and is separate from the vaccination appointment. Bring the red book, questions and a list of medicines or supplements.

For children reaching 1 under the current England schedule, the appointment includes the first MMRV dose for children born on or after 1 January 2025, plus the pneumococcal booster and third MenB dose. Date of birth and UK nation can affect the exact programme, so follow the invitation and check the personal record with the GP practice. Do not delay or repeat a dose from a generic online table.

08

Home safety and when to seek help

Anchor furniture and televisions, fit stair gates and window safeguards, and lock away button batteries, strong magnets, medicines, cleaning products, cords, hot drinks and small objects. A baby who is not walking can still reach danger by crawling or pulling up. Never leave a child alone near water or on a raised surface.

Contact the GP or NHS 111 promptly for loss of a skill, marked asymmetry, reduced response to sound, repeated distress with eating or a persistent developmental concern. Seek urgent same-day help for inability to drink, repeated forceful or green vomit, blood in stool, much less urine, a rash that does not fade under pressure or unusual drowsiness. Call 999 now for breathing difficulty, blue or grey skin, seizure, extreme difficulty waking, serious injury, suspected button-battery or strong-magnet ingestion, or facial swelling with wheeze after food.
