Your baby at 5 months: grabbing everything and starting to sit
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.
What is new this month
Reaching becomes accurate. A five-month-old sees something, reaches with both hands, gets it, and takes it to the mouth — which is how babies of this age learn shape and texture. Your hair, your glasses, your plate and the hot cup of tea are all now within range.
Sitting begins: propped on cushions, then tripod-sitting on their own hands for a few seconds. Most babies sit unsupported somewhere between six and eight months, and this is the practice month.
Rolling is usually solid in at least one direction, and some babies start pivoting in circles on their tummy — the first hint of moving with intent. Babbling gains consonants: ba, da, ma, in long strings.
Safety changes this month
A baby who can reach and roll is a baby who can reach a hot drink, a phone charger, a plate of food or the edge of the bed. Move tea and coffee away from the floor and the low table, and never hold a hot drink while holding the baby.
Everything within a metre of the floor gets a check: coins, buttons, pins, blister packs of medicine, small toys belonging to older siblings, and cords or chains. If it passes through a toilet-paper tube, it is a choking hazard.
In an Indian home, three specific ones: buckets of water — a baby who can roll can also topple in and cannot get out; the mosquito coil or heater at floor level; and the pressure cooker or hot vessel set down to cool on the ground.
Sleep and feeding
Most five-month-olds sleep around 12-15 hours in 24, with three naps that gradually consolidate into two. Night waking is still normal, including in babies who once slept through.
Milk remains the whole diet — this is not the month for solids unless your paediatrician has specifically advised it for growth or reflux reasons. Watch instead for the readiness signs building: sitting with support, head steady, interested in your plate, tongue-thrust reflex fading.
Growth slows a little compared to the first months, and weight gain of around 400-600 g a month is typical now. The growth chart, not a single weighing, is what tells you whether things are on track.
When to see a doctor
The standing newborn rules still apply: any fever in a baby under three months means the hospital the same day; fast or laboured breathing, the chest sucking in, blue lips, a fit, a rash that does not fade under pressure, refusing feeds, no wet nappy for six to eight hours, or a baby who is floppy and hard to wake are all same-day emergencies at any age.
This month specifically: not reaching for objects, not bringing hands together, no babbling or vocal turn-taking, not rolling in any direction by six months, a marked preference for using only one hand, or persistent stiffness or floppiness.

Frequently asked questions
Can I use a walker to help him learn to walk?
No. Walkers slightly delay walking, encourage toe-walking, and cause serious injuries when they tip or reach stairs — several countries have banned them. Floor time and later a push toy do the job safely.
He drools constantly and chews his fist
is a tooth coming? — Possibly, and possibly not. Some babies drool for months before the first tooth. Wipe the chin often and use a barrier cream against the rash.
Should I prop him up with cushions to sit?
Supervised, briefly, on the floor with cushions around him, yes. Do not leave a propped baby unattended, and skip the seats that hold a baby upright for long stretches — floor time builds the muscles that sitting needs.
My baby wakes for two night feeds. Is that too many at five months?
Entirely normal. Night feeds commonly continue to six months and beyond, particularly for breastfed babies.

- WHO. WHO Child Growth Standards: Growth velocity based on weight, length and head circumference (2009)Backs the claim that growth slows after the early months and that a growth chart rather than a single weighing is the appropriate way to assess whether weight gain is on track.
- WHO. Guideline: Complementary feeding of infants and young children 6–23 months of age (2023)Backs the statement that milk remains the whole diet at five months and that solids should not be introduced before six months in the absence of specific clinical indication.
- AAP. Baby Walkers: A Dangerous Choice (2023)Backs the Q&A answer that walkers delay walking, promote toe-walking, and cause serious injuries from tipping or stair falls, and that floor time is the safer alternative.
- NICE. Fever in under 5s: assessment and initial management (NG143) (2021)Backs the emergency red-flag list including fast or laboured breathing, chest recession, cyanosis (blue lips), seizures, non-blanching rash, poor feeding, reduced wet nappies, and a floppy or difficult-to-rouse baby as same-day emergencies at any age.
