Your 23-Week-Old Baby

Sitting with support steadies around now, hands are busy exploring, and the solid-food stage is on the horizon rather than here.

Milestones describe common patterns, not deadlines. Every baby develops at their own pace.

This shows time in the first year, not how your baby is developing.

This week at a glance

Movement

Sits with support; may sit steadier soon.

Communication

Babble and laughter grow expressive.

Feeding

Milk-led; watching for solids-readiness signs.

Sleep

Three naps and a longer night are common.

These are common patterns for this stage, not requirements for this exact week.

Development and milestones

Movement

  • Sits with support
  • Rolls both ways for some babies
  • Reaches with purpose

Thinking and understanding

  • Mouths objects to learn them
  • Looks for a partly hidden toy

Communication

  • Longer babble
  • Laughs at silly faces

Social and emotional development

  • Studies new faces
  • Reaches for carers

Sitting and first foods arrive across a wide range — not reaching them this exact week can be completely typical.

Feeding

Around 6 months is the usual window to add solids while breast milk or infant formula stays the main source of nutrition. Start small and follow your baby's interest.

  • Look for readiness — steady head control, sitting with support, interest in food
  • Offer simple iron-containing first foods (dal, khichdi, ragi, soft fruit)
  • A few spoons once a day, building up gradually
  • Continue breast milk or infant formula
  • No honey and no added salt or sugar in the first year
  • Introduce common allergens one at a time, per your paediatrician

Feeding safety

  • Sit your baby upright and supervise every meal
  • Offer soft, mashed or safely shaped foods
  • Avoid whole nuts and hard, round foods
  • Learn the difference between gagging (normal, noisy) and choking (silent)
View choking prevention guidance (NHS)

Sleep

Common sleep pattern

Many babies begin consolidating night sleep with two to three naps, though regressions can still happen.

Why sleep may change

  • Growth spurts
  • Rolling and new skills
  • Teething
  • Changes in routine

What may help

  • A predictable bedtime routine
  • Consistent nap timing where it works
  • A calm wind-down
  • A consistent sleep environment

Safe sleep reminder

  • Place your baby on their back to begin sleep
  • Use a firm, flat sleep surface
  • Keep pillows, bumpers, toys and loose bedding out of the cot

Play and activities

Supported sitting

Supports: Trunk control

Sit your baby with cushions and safe toys.

Safety: Stay within arm's reach.

Cause and effect

Supports: Learning

Offer a rattle or crinkly toy.

Safety: No small parts.

Face-to-face chats

Supports: Language

Pause after your baby 'talks' and reply.

Safety: Gentle and close.

Mirror play

Supports: Social smiling

Let your baby watch their reflection.

Safety: Baby-safe mirror.

Babyproof before the next step

Mobility safety matters a lot at this stage. A quick sweep now keeps new skills safe.

  • Never leave your baby alone on a raised surface
  • Keep small objects and choking hazards off the floor
  • Use high-chair straps once sitting for meals
  • Keep hot food and drinks away from the edge
  • Begin planning outlet covers and stair gates

Growth

Growth is a pattern, not a weekly target.

What matters most

  • Weight, length and head circumference tracked over time
  • Whether your baby keeps following their own growth pattern
  • Feeding, energy and overall wellbeing
  • Any sudden change in the growth curve

Percentiles are read alongside the overall pattern — not used to diagnose on their own.

Vaccinations to check

There is no universal vaccine assigned solely to Week 23. What is due depends on several things, so check your baby's record rather than assuming a schedule.

What is due depends on:

  • Previous doses already given
  • The Universal Immunization Programme (UIP) schedule
  • The Indian Academy of Pediatrics (IAP) schedule
  • Your state programme
  • Your paediatrician's guidance
  • Any catch-up requirements

If you are signed in with a baby profile, your next recorded vaccine appears on your dashboard. Always confirm timing with your paediatrician.

When to contact a doctor

Seek urgent medical care

  • Breathing difficulty or blue lips/face
  • A seizure or loss of consciousness
  • Baby is very difficult to wake or unusually floppy
  • A serious fall or head injury
  • Signs of severe dehydration
  • Persistent vomiting with a worsening condition

Discuss promptly with your paediatrician

  • Not sitting with support
  • Not babbling or responding to sounds
  • Not reaching for or exploring objects
  • Very stiff or very floppy muscle tone
  • Loss of a previously acquired skill

Loss of a previously acquired skill should be discussed promptly.

ParentVibes offers general information, not medical advice or diagnosis. If you are worried, contact your doctor.

What comes next

Coming next: Week 24

In the coming week you may notice more of the patterns below as your baby grows — every baby at their own pace.

You may notice

  • Sitting hands-free and pivoting to reach
  • A wider range of textures at mealtimes
  • First attempts to move — rocking or shuffling

One safety reminder

Never leave your baby alone on a raised surface

One play idea

Offer a shallow basket of safe objects.

Helpful for this stage

Frequently asked questions

How do I know when my baby is ready for solids?

Readiness signs include steady head control, sitting with support and interest in food, usually around 6 months. Check with your paediatrician before starting.

Why does my baby mouth everything?

Mouthing is normal exploration and eases teething. Keep small objects out of reach and offer safe teethers.

Is three naps normal at 5 months?

Yes — nap numbers vary and shift over the coming months. Follow tiredness cues and keep a calm wind-down.

How much water can my baby have?

Once solids start, small sips of cooled boiled water with meals are generally fine, while breast milk or formula still provides most fluids. Check with your paediatrician if you're unsure.

Which foods should I avoid?

Avoid honey and added salt or sugar in the first year, and whole nuts or hard round foods. Introduce common allergens one at a time as your paediatrician advises.

When is the next vaccination?

Vaccination timing depends on your baby's record and the schedule your paediatrician follows. Check the immunisation card and confirm the next date with your clinic.
