Your baby's first year, month by month

What to expect, little things to try, and when to call the doctor — so the app grows right alongside your little one. Remember: every baby blooms on their own schedule.

Soft illustration of babies growing at their own pace

These months are a map, not a race. A skill landing a little earlier or later is normal — the ranges are months wide. And you never need a milestone list to call a doctor: if something feels wrong, your instinct is reason enough.

Newborn (0–1 month)

What you might see
  • Sleeps 14–17 hours in short stretches, waking to feed every 2–3 hours.
  • Sees best at 20–30 cm — exactly the distance to your face while feeding.
  • Startles at sounds, grips your finger, turns toward your smell and voice.
  • Crying is their only language right now — it does not mean you're doing anything wrong.
Gentle things to try
  • Skin-to-skin cuddles — calming for baby and boosts milk supply.
  • Talk and sing softly; your voice is their favorite sound.
  • Short supervised tummy time (1–2 minutes) a few times a day while awake.
When to call the doctor
  • Fever of 38°C (100.4°F) or higher — for babies under 3 months this is always urgent.
  • Fewer wet diapers than expected, refusing feeds, or unusual limpness or unresponsiveness.
  • Yellowing skin or eyes that spreads or deepens (jaundice check).

1–2 months

What you might see
  • First real smiles appear — often around 6 weeks. They are smiling AT you.
  • Starts cooing and making small sounds back when you talk.
  • Holds their head up briefly during tummy time.
  • May have a fussy period in the evening ('witching hour') — very common and it passes.
Gentle things to try
  • Smile, coo, and pause — early 'conversations' teach them turn-taking.
  • Follow their cues: when they look away, they need a little break.
  • Keep feeding on demand; growth spurts around 6 weeks mean extra hungry days.
When to call the doctor
  • Fever of 38°C (100.4°F) or higher — still urgent under 3 months.
  • Not responding to loud sounds, or not watching faces by 2 months.
  • Feeding problems, vomiting most feeds, or fewer than 6 wet diapers a day after day 5.

2–3 months

What you might see
  • Smiles, coos, and 'talks' more; may laugh out loud.
  • Pushes up on forearms during tummy time; head control grows steadier.
  • Discovers their hands and brings them to their mouth.
  • Some babies begin sleeping one longer stretch at night (4–6 hours).
Gentle things to try
  • Tummy time little and often — aim for short sessions spread across the day.
  • Read to them daily; it doesn't matter what, your voice is the magic.
  • A loose daily rhythm (feed, play, sleep) helps — but stay flexible.
When to call the doctor
  • Fever of 38°C (100.4°F) or higher — urgent until 3 months old.
  • Doesn't smile at people, doesn't follow moving objects with their eyes.
  • Very stiff or very floppy body, or always holding one side differently.

3–4 months

What you might see
  • Laughs, squeals, and bats at dangling toys.
  • Rolls from tummy to side, sometimes all the way over — never leave them on a raised surface.
  • Sleep may temporarily get choppier around 4 months (the famous 'regression') — it's a sign of a maturing brain.
  • Everything goes in the mouth. This is learning, not bad behavior.
Gentle things to try
  • Offer safe teethers and textured toys to explore with their mouth.
  • Floor play on a blanket beats time in seats and swings.
  • If sleep changed, keep the bedtime routine calm and consistent — it passes.
When to call the doctor
  • Fever of 38°C (100.4°F) or higher under 3 months; after 3 months call for fever with unusual behavior, poor feeding, or fewer wet diapers.
  • Doesn't reach for things, doesn't respond to your voice, or can't hold their head steady.
  • Any rolling means sleep must stay on their back on a flat, empty surface — ask your doctor if unsure.

4–5 months

What you might see
  • Rolls both ways, grabs toys, and transfers them hand to hand.
  • Babbles with more sounds — 'ba', 'ma', 'da' — without meaning yet.
  • Recognizes familiar faces and may get shy or clingy with strangers.
  • Watches you eat with great interest — but most babies aren't ready for food yet.
Gentle things to try
  • Play peekaboo — it teaches that you always come back.
  • Give them safe household objects (wooden spoon, cloth) to explore.
  • Talk through your day; narrating builds their language long before they speak.
When to call the doctor
  • Doesn't make sounds, doesn't watch things move, or seems very stiff or floppy.
  • No interest in reaching or grabbing by 5–6 months.
  • Any fever in a young baby with poor feeding, unusual sleepiness, or fewer wet diapers.

5–6 months

What you might see
  • Sits with support, then briefly alone; pushes up on straight arms.
  • Around 6 months, most babies show signs of readiness for first foods: sitting with support, good head control, and reaching for food.
  • Responds to their name and babbles happily back and forth.
  • Stranger wariness can begin — a healthy sign of attachment to you.
Gentle things to try
  • If your doctor agrees, offer simple first tastes — soft avocado, banana, well-cooked sweet potato. Food before one is mostly for learning.
  • Keep breast milk or formula as the main food through the first year.
  • Practice sitting on the floor with cushions around, always supervised.
When to call the doctor
  • Before starting solids if your baby was premature or has any feeding difficulties.
  • Doesn't respond to sounds or their name, or makes few sounds.
  • Signs of an allergic reaction to a new food: hives, swelling, vomiting, or trouble breathing (emergency).

6–7 months

What you might see
  • Sits without support, may start rocking on hands and knees.
  • Enjoys dropping, banging, and shaking everything — this is science, baby-style.
  • Separation anxiety may appear; tears when you leave mean they love you, not that you're spoiling them.
  • First teeth may appear — drooling, chewing, and crankiness are normal.
Gentle things to try
  • Chilled (not frozen) teethers and a clean cold washcloth soothe sore gums.
  • Practice gentle goodbyes — always say goodbye instead of sneaking out.
  • Continue slow, pressure-free solids alongside milk feeds.
When to call the doctor
  • Fever with teething — teething does NOT cause real fevers, so a fever means something else.
  • Doesn't sit with support or bear weight on legs when held upright.
  • Not babbling or making eye contact.

7–8 months

What you might see
  • Many babies start crawling — but some shuffle, scoot, or skip crawling entirely. All are normal.
  • Everything on the floor is now within reach — this is the moment to baby-proof.
  • Understands 'no' and their name; may start waving.
  • Sleep can wobble again as they practice new skills at night.
Gentle things to try
  • Get down on your hands and knees and see the room from their height — remove anything small enough to choke on.
  • Create one fully safe 'yes space' where everything is allowed.
  • Keep putting phones down during play — crawling games with YOU beat any toy.
When to call the doctor
  • Uses one side of the body much more than the other.
  • Doesn't babble, bear weight on legs, or show interest in people.
  • Any choking incident, fall from a height, or head bump with vomiting or unusual sleepiness — seek care right away.

8–9 months

What you might see
  • Crawls, pulls to stand, and cruises along furniture.
  • Pincer grasp develops — picks up tiny things between finger and thumb (watch the floor!).
  • Understands simple words; may say 'mama' or 'dada' — sometimes to the wrong parent, and that's fine.
  • Separation anxiety often peaks — predictable routines help.
Gentle things to try
  • Offer soft finger foods they can pick up themselves, always supervised and in safe sizes.
  • Play hiding games with toys under a cloth — object permanence practice.
  • Anchor furniture and check blind cords now — climbers surprise you.
When to call the doctor
  • Doesn't bear weight on legs, sit steadily, or babble by 9 months.
  • Seems to lose skills they once had — always worth a prompt call.
  • Button battery or magnet swallowing is an emergency — go to ER immediately, do not wait.

9–10 months

What you might see
  • Stands holding on, may let go for a wobbly second.
  • Waves, claps, and points at interesting things.
  • Copies sounds and gestures — they're watching everything you do.
  • May test 'no' with a grin. Gentle, consistent limits start here.
Gentle things to try
  • Clap, wave, and copy games — take turns.
  • Name everything during the day: 'cup', 'water', 'up we go'.
  • A cupboard with safe items (pots, lids, spoons) is the best toy in the house.
When to call the doctor
  • Doesn't respond to their name or make eye contact.
  • Not babbling or using gestures like waving or pointing.
  • Any loss of skills they previously had.

10–11 months

What you might see
  • Cruises confidently; some take first independent steps — others walk months later. Both are normal.
  • Says one or two words with meaning; understands far more than they say.
  • Loves cause-and-effect: dropping food from the high chair is physics, not naughtiness.
  • May show stranger and separation feelings strongly — stay patient and warm.
Gentle things to try
  • Barefoot practice at home helps balance; shoes are for outdoors.
  • Push-toys (weighted and stable) are safer fun than sit-in walkers, which are best avoided.
  • Keep offering a variety of family foods in safe textures.
When to call the doctor
  • Doesn't crawl or move around in some way by 12 months.
  • Can't stand with support or doesn't use gestures.
  • Concerns about hearing — not turning toward sounds or voices.

11–12 months

What you might see
  • First birthday! May walk independently or soon — the range of normal is wide (9–17 months).
  • Says a few words, follows simple requests, and points to show you things.
  • Shows clear preferences — people, toys, foods — a personality blooming.
  • The 12-month check-up and vaccinations are usually due around now.
Gentle things to try
  • Celebrate how far you BOTH have come. You kept a small human alive and loved for a year.
  • Keep reading together daily — board books they can handle themselves.
  • Around the birthday, your doctor can guide the shift from formula or breast milk patterns to more family foods.
When to call the doctor
  • Keep the 12-month well-baby visit — growth, development, and vaccines are checked there.
  • Not standing with support, not using gestures, or no words yet — mention it at the visit.
  • Trust your gut always: if something feels wrong, you never need to wait for a milestone list to call.

Trust your gut, always. You know your baby better than any chart — including this one. Asking for help is never an overreaction; it is good mothering.
