Child Development 3 Six To Nine Months

Overview

The months between 6 and 9 are a busy, exciting stretch of a baby's life. Your baby is moving from being a small, settled newborn to a curious little person who reaches, rolls, sits, babbles and starts to eat solid food. This article explains the changes you may see, what you can do to help, and the signs that mean it is worth checking in with your health visitor or doctor. Every baby follows their own timetable, so use this as a general guide, not a checklist to score your child against.

Yes. Every baby goes through this stage, and the milestones described here are the everyday pattern of development for most children. Small differences in timing are very common and usually not a sign of a problem.

All babies between about 6 and 9 months old, and the parents and carers looking after them. Babies born early may take a little longer to reach some milestones, and your health visitor will usually adjust for this when checking progress.

Symptoms

Common symptoms

• Rolling from tummy to back and later from back to tummy.
• Sitting with support, and for some babies sitting without help by around 9 months.
• Reaching for toys, grabbing them, and moving them from one hand to the other.
• Putting almost everything in the mouth as a way of exploring.
• Babbling strings of sounds like 'ba ba' or 'da da', and copying your sounds.
• Turning the head towards a voice or a noise.
• Recognising familiar faces and showing shyness or wariness around strangers.
• Enjoying simple games like peekaboo.
• Starting to bear weight on the legs when held standing.
• Some babies begin to shuffle, creep or crawl towards 9 months, while others wait longer.

Symptoms in children

• Your baby may become more settled in sleep patterns, or go through a patch of poorer sleep as new skills keep them busy.
• Teething may start around this time, bringing dribbling, gum rubbing and occasional fussiness.
• Your baby may show clear likes and dislikes, and protest when a toy is taken away.
• First solid foods begin, so expect messy meals and changing nappy patterns.
• Some babies show a strong preference for one hand or one side, but using both hands is more typical at this age.

Symptoms in older adults

• Not applicable. This topic is about babies aged 6 to 9 months.

Causes

Main causes

• Rapid brain and nerve growth, which is what allows new movement, understanding and communication skills to appear.
• Practice and play. Babies learn by repeating actions, watching faces and exploring safe objects.
• Good nutrition, including breast milk or first infant formula alongside solid foods from around 6 months.
• Enough sleep and rest, which helps learning and mood.
• Being talked to, sung to and read to, which builds language skills long before first words.
• Natural differences between children. Genes and temperament both play a part in how and when skills appear.

Risk factors

• Being born prematurely, which can mean milestones arrive a little later at first.
• Hearing or vision difficulties, which can slow talking or movement learning if not picked up.
• Long or repeated illnesses in early months.
• Very little chance to play on the floor, move freely or hear conversation.
• Family stress or a carer who is struggling with their own health, which can make it harder to get support in place early.
• Some medical conditions affecting muscles, nerves or development, which your health visitor or doctor will look for if there are concerns.

When to see a doctor

See a doctor urgently if:

• Your baby has a fever and seems unwell, is not feeding, or is much sleepier than usual.
• Your baby has a fit, or goes stiff, floppy or unresponsive.
• Your baby stops breathing, struggles to breathe, or turns blue or grey.
• Your baby has a rash that does not fade when pressed.
• Your baby has a head injury, a serious fall, or has swallowed something that could be harmful.
• Your baby loses a skill they already had, or suddenly stops using one arm or leg.
• You have any gut feeling that something is seriously wrong.

Book a routine appointment if:

• Your baby does not seem to turn towards sounds or does not babble by around 9 months.
• Your baby does not reach for or hold toys, or keeps their hands in tight fists most of the time.
• Your baby has not rolled over in either direction by around 7 to 8 months.
• Your baby cannot sit even with support by around 9 months, or feels very stiff or very floppy when you hold them.
• Your baby does not smile in response to you, or does not seem to recognise familiar people.
• One eye turns in or out, or your baby does not seem to see things clearly.
• You are worried about feeding, weaning, sleep, growth or behaviour.
• You are feeling low, anxious or overwhelmed, or finding it hard to cope.

Diagnosis

There is usually nothing to diagnose, because this stage is a normal part of growing up. Your health visitor or doctor checks progress by watching your baby, asking you questions about what your baby can do, and sometimes using a simple checklist of milestones. This is done at routine reviews, and any time you raise a concern.

Tests that may be done

• A physical examination, including checking muscle tone, movement, head control and growth.
• Watching how your baby responds to your voice, to a toy and to being picked up.
• A hearing check if there is any doubt about your baby's response to sound.
• A vision check and a look at eye movements and eye reflections.
• Questions about feeding, sleep, play and what your baby can do at home.
• A blood test only if your doctor thinks there may be a reason, such as anaemia or another health condition.
• Referral to a child development specialist if a concern needs a closer look, which does not mean something is definitely wrong.

What to expect at your appointment

Appointments are usually relaxed and play-based. Your baby may be watched while playing on a mat, and you will be asked what they do at home. Bring any notes from other reviews if you have them. You will usually be told whether anything needs following up, and what happens next. If a referral is made, waiting times vary, so ask what to expect and who to contact with questions.

Treatment

This stage does not need medical treatment. What helps most is everyday care: feeding well, plenty of floor play, lots of talking and cuddling, and safe chances to explore. If a difficulty is found, such as a hearing problem or a delay in movement, early support can make a real difference, which is why checks at this age are valuable.

Self-care at home

• Give your baby time on the floor every day, on their tummy while awake and supervised, and on their back to play.
• Talk, sing and read together. Name things, copy your baby's sounds and pause to let them answer.
• Offer safe toys to hold, bang and mouth, such as soft blocks, rings and cloth books.
• Start solid foods at around 6 months with soft, iron-rich foods, and let your baby feed themselves with fingers.
• Keep breast milk or first infant formula as the main drink. Do not give added salt, sugar or honey before 12 months.
• Keep routines for meals and bedtime calm and predictable, which helps your baby feel secure.
• Make the home safe before crawling starts: cover sockets, secure cupboards, and keep small objects and hot drinks out of reach.
• Look after yourself too. Rest when you can, accept help, and talk to someone if you feel low.

Medical treatments

If a concern is found, support may include a referral to a hearing or vision service, physiotherapy to help with movement, or speech and language therapy for feeding or early communication. Your doctor will explain any options and you will be involved in decisions at every step. Routine childhood immunisations are also offered at set ages and are an important part of keeping your baby healthy; your clinic will tell you what is due.

When is surgery considered?

Surgery is not relevant to this topic. Very occasionally a child with a specific medical condition may need an operation, but that would be discussed separately by a specialist.

Living with this condition

Days with a 6 to 9 month old are busy. Your baby is likely to want company, movement and things to grab, and will tire quickly and need naps. Try to keep a gentle rhythm of feeds, naps, floor play and outings. Messy eating and disrupted sleep are normal parts of this stage and pass with time.

Lifestyle tips

• Create a safe play area on the floor where your baby can roll, stretch and practise sitting.
• Keep small objects, cords, hot drinks and medicines well out of reach as mobility begins.
• Use a car seat correctly on every journey, and never leave your baby alone on a changing table, bed or sofa.
• Share care where you can, and take short breaks to recharge.
• Meet other parents if possible. Baby groups and local family services are good places for support and practical tips.
• Keep up with health visitor and clinic appointments, and note any questions as they come to you.

Diet and exercise

Breast milk or first infant formula stays the main drink, with solid foods starting at around 6 months and building up over the following weeks. Offer a variety of soft textures and iron-rich foods such as mashed beans, lentils or well-cooked meat, alongside fruit and vegetables. Avoid honey, whole nuts, added salt and added sugar. Water can be offered in an open or free-flow cup with meals. For movement, floor time is the best exercise: rolling, reaching, sitting practice and, later, crawling and pulling up. Baby walkers are not recommended.

Mental health and emotional wellbeing

This can be a joyful but exhausting time. Broken sleep, constant feeding and weaning, and less time for yourself can leave you feeling drained, tearful or anxious. Many parents feel this way, and it is not a failure. Talk to your health visitor or doctor if low mood, worry or frightening thoughts last more than a couple of weeks or affect daily life, because help is available and works well. If you ever feel you might harm yourself or your baby, please call your local emergency number or a crisis support line straight away, and stay with someone you trust until help arrives.

Prevention

Development itself cannot be prevented, because it is exactly what we want to happen. What can be supported is a good environment for it: good nutrition, safe chances to move and play, plenty of talking, enough sleep, and keeping up with health checks and immunisations. Early help for any difficulty gives a child the best chance to thrive.

Vaccines

Routine childhood immunisations are offered on a set schedule to protect your baby from serious infections. Your clinic or health visitor will tell you which ones are due and when. If you have missed an appointment or are unsure, ask your doctor or pharmacist how to catch up.

Screening programmes

Routine developmental reviews, hearing checks and growth measurements are offered in the first year and beyond. These check-ups are a good chance to raise any worry early. Bring your personal child health record, often called the red book, to every appointment.

Complications

If left untreated

• A hearing or vision problem may go unnoticed and slow early talking or learning.
• A movement difficulty may make sitting, crawling or walking harder without the right support.
• Feeding or growth problems may be missed if concerns are not shared.
• Parents may struggle alone with worry or low mood when help was available.

Long-term outlook

The outlook for this stage is very positive. Most babies move through these months without any difficulty and go on to walk, talk and explore with confidence. Where a problem is found, early support often works well, and children are remarkably good at catching up with the right help. Keep talking to your health visitor or doctor, and trust your instincts about your own child.
