Baby Development

The first twelve weeks — the ones that feel longest and pass fastest. A page for every week: what changed in the baby, how the mother is, what to do, and when to see a doctor at once.

Twelve months, one page. What changes each month, what to feed, what to expect from sleep, which vaccines fall when — and the short list of signs that always mean a doctor.

Crawling is the milestone parents worry about most and the one that matters least. What matters is whether a baby is finding some way to move.

The normal range for first steps is far wider than the family group chat suggests. Most late walkers are simply late walkers.

The most important sentence of week one: newborns lose weight, and it is not an illness. This page gives both lists plainly — what's normal, and what means hospital the same day.

The health-centre queue again this week — the second vaccine visit. And back home, perhaps, the sound that fades every other sound in the world: the first proper laugh.

The swatting hand now learns to hold — whatever reaches the palm is captured, and heads straight for the mouth. And from the mouth flows this week's other news: drool, by the bucket.

Twelve weeks — the fourth trimester complete. The newborn who arrived is now a smiling, laughing, grasping, 'talking' person. This page is the quarter's report card — and the next quarter's preview.

This week hands you a receipt — birth weight regained, which means the milk supply is working. And a test — a baby wide awake at 3 am who sleeps all day.

Suddenly hungry every hour? Don't panic — it's the first growth spurt, a two-to-three-day storm. And this week life's first workout begins: a few minutes on the tummy.

The first month complete — the tunnel of the longest four weeks is behind you. The baby now 'sees', pauses to listen, and is testing its first sounds.

This is when the moment comes that forgives every lost night — the baby looks at you, knows you, and smiles. Not a sleep-smile; one for you.

Two dates on this week's calendar — the baby's and the mother's. The vaccine visit is the baby's shield; the six-week check is the mother's. Neither is optional.

This week the baby discovers something astonishing — its own hands. The long staring, the fist steered to the mouth — not idle play; the body's map is being drawn.

Two months complete — and the best news is that the evening storm is now in descent. Smiles are daily, the night stretch is lengthening, and the household's breathing is settling.

Until now things came to the baby; from this week the baby goes to things — the first wild swing at a dangling toy is intention's first letter home.

Nearly every Indian toddler is brought to a doctor for bowed legs or flat feet at some point. Almost all of it is normal development — and a small proportion is vitamin D deficiency, which is common here and treatable.

Height is mostly inherited, and the part that is not is decided by nutrition, sleep and health — none of which comes in a bottle.

The best shoe for a new walker is no shoe. Once they are outdoors, a small number of things matter and most of what is sold does not.

Almost every one of these gets searched at midnight by a frightened parent, and almost every one has the same answer: common, self-soothing, and outgrown. Here is each of them, and the small number of signs that change the answer.

Weight gets all the family's attention and head circumference gets the doctor's, because it is the measurement that tracks the brain.

Every Indian family has an opinion about whether the baby is thin. Here is what the numbers actually look like, and which ones matter.

Half of all healthy babies are below the fiftieth percentile — that is what a fiftieth percentile means. Here is how to read the chart your doctor is plotting.

A new walker falls roughly every couple of minutes of walking. Almost all of it is how walking gets learned — and a small number of falls need a hospital.

Month one is not about milestones. It is about feeding, nappies, sleep in fragments, and learning which cries mean what — for both of you.

Ten months is when a baby starts joining the family properly — eating a toned-down version of your food, and using a sound that means something.

Eleven months brings the first real frustration — a baby who knows exactly what they want, cannot say it, and now has the mobility to go and get it.

One year old. Birth weight has roughly tripled, milk is no longer the main meal, and a set of rules that ran the whole first year quietly expires.

Month two brings the first real smile and the first big vaccination visit — and, for most families, the peak of the crying.

Three months in, the newborn phase closes. The crying drops, the sleep lengthens, and a baby with opinions appears in its place.

Four months brings the first belly laugh and, for most families, the first sleep collapse. Both are signs of the same thing — a brain that has just reorganised itself.

At five months a baby stops watching the world and starts grabbing it. Everything within reach is now fair game — and everything goes straight into the mouth.

Six months is the biggest turning point of the first year: solids begin, iron stores run low, and the baby who could only watch can now sit and join in.

Seven months brings two things at once: a baby who is learning to move, and a baby who has just worked out that you can leave the room.

At eight months a baby stops being a passenger. They pull themselves up, pick up a single grain of rice, and have loud opinions about being put down.

Nine months is a milestone visit as much as a milestone month: the measles-rubella vaccine is due, and it is one of the ones you do not let slide.
