Your baby at 9 to 10 months: development, cruising and communication

6-12 months · Development · Reviewed 20 June 2026 · All articles

Nine and ten months is when many parents first get the sense that their baby has intentions. Not just reactions, but actual plans. They crawl purposefully toward something they want. They pull to stand with evident determination. They look at you while doing something they know they are not supposed to do. They hand you a toy and wait to see what you do with it. The cognitive and social development happening at this age is striking, and it shows.

As with all developmental milestones, the timings described here are ranges, not rules. Some babies will reach particular milestones a few weeks earlier, others later. Individual variation is the norm in child development, and a baby who is a little behind on one area while forging ahead in another is typically developing completely normally. What follows is a guide to what the period between 9 and 10 months often looks like.

At a glance: 9 to 10 months

Physical development and motor skills

Pulling to stand is one of the headline milestones of this period. Most babies achieve it somewhere between 8 and 11 months. They will grab the edge of the sofa, the bars of their cot, your legs, or any other conveniently placed solid surface and haul themselves upright. The first attempts often look effortful and a little precarious, but within days most babies become very efficient at getting up, even if coming back down is trickier. Falls backward from standing are common; a carpeted or padded environment helps reduce the impact.

Cruising, moving sideways along furniture while holding on, tends to follow shortly after a baby can pull to stand reliably. It is the bridge between standing with support and independent walking, and it is fascinating to watch because you can see your baby problem-solving in real time: reaching a little further, shifting weight from foot to foot, figuring out corners. There is no need to use baby walkers to help with this process; furniture, a low stable push toy, or your hands are all that is needed.

Some babies at 10 months stand briefly unsupported, perhaps for a second or two before they realise what they are doing and sit down. This is perfectly normal. Independent standing and first steps can come anywhere from 9 to 15 months, and being at the later end of this range does not indicate a problem.

The pincer grasp, using the tip of the index finger and the thumb to pick up small objects, is developing through this period. Earlier in the first year babies use a raking grasp, sweeping objects toward the palm. The emergence of the pincer grasp is a significant fine motor milestone that opens up a great deal: picking up small pieces of food, turning pages in a board book, and exploring tiny objects with much greater precision. By 10 months many babies have a fairly reliable pincer grasp, though it continues to refine over the months that follow.

Clapping is another motor and social milestone that appears for many babies around 9 to 10 months. It is partly a physical skill and partly a social one, since babies often clap in response to encouragement or as a way of showing pleasure. It also appears in games like pat-a-cake, which remains a favourite activity at this age.

Feeding at 9 to 10 months

By 9 to 10 months most babies are established on three solid meals a day. The texture picture has expanded considerably: lumpy, mashed, and soft-chunky foods are appropriate now, and many babies are managing a good range of soft finger foods alongside or instead of spoon-fed purees. Self-feeding grows in confidence through this period as the pincer grasp improves, and babies often show strong preferences for feeding themselves over accepting spoon-fed food.

Milk continues to be an important part of the diet through the first year. Formula-fed babies typically take around 500 to 600 ml per day at this stage, usually spread across a morning and evening feed with solid meals in between. Breastfed babies will nurse at a frequency that varies considerably between families; there is no single right amount. The pattern of nursing morning and evening around solid meals is common, but every feeding relationship is individual.

A wide variety of foods is the goal rather than large portions. Offering a range of vegetables, fruits, grains, proteins, and dairy products at this stage builds the foundation of a varied diet and reduces fussiness later. Research suggests that exposure to a wide range of flavours and textures in the first year has lasting effects on food acceptance. If your baby refuses a new food, try again on another day without pressure. It often takes multiple exposures before a new food is accepted.

Iron remains an important nutrient at this age. Continuing to include iron-rich foods such as meat, fish, eggs, lentils, and fortified cereals at most meals helps maintain adequate stores. Vitamin D supplementation is recommended for most babies; check current guidance from your health visitor or GP for the specific recommendation that applies.

Sleep at 9 to 10 months

Sleep remains highly variable at this age. Many babies are still waking at night, and the separation anxiety that is strong through this developmental period means that some babies who previously slept reasonably well may have regressed. This is normal and not a permanent state.

Most babies at 9 to 10 months take two naps: one in the mid-morning and one in the afternoon. Total daytime sleep is typically around two to three hours. Some babies begin transitioning toward longer, less frequent naps during this period. Total sleep across 24 hours averages around 12 to 15 hours, though meaningful variation exists at both ends.

Night feeds are still common and nutritionally appropriate for many babies at this age, particularly those in the lighter weight range or going through growth periods. The decision about whether and how to reduce night waking is a personal one that depends on your family's circumstances, values, and overall wellbeing. There is no single correct answer. If sleep has become a significant issue for your family, a conversation with your health visitor about evidence-based options is a good starting point.

Communication and social development

The first intentional word is one of the most anticipated milestones of the first year, and for many babies it arrives somewhere between 9 and 14 months. An intentional word means a sound that is used consistently to refer to a specific person, object, or concept, as distinct from babbling. "Mama" directed at the mother, "dada" at the father, or a name for a pet or favourite toy are common first words. The sound does not need to be perfectly pronounced; the consistency and intentionality of its use is what matters.

Babbling at 9 to 10 months is increasingly conversational in its rhythm. Babies at this age begin to understand the back-and-forth structure of dialogue: they babble, pause, and look at you as if awaiting a response. Responding, even if only with interest and simple language, is one of the most effective things you can do to support language development. This serve-and-return pattern of interaction is well-evidenced as a foundation for language and communication.

Pointing emerges as a key communicative tool around this period, most typically between 9 and 12 months. Proto-declarative pointing, where a baby points at something interesting to share it with you rather than to request it, is particularly significant because it indicates an understanding that other people have minds and interests that can be directed. When your baby points at a bird outside the window and looks back at you, they are inviting you into their experience, which is a remarkable social development.

Following simple instructions becomes possible for many babies at this age. "Come here," "give it to me," and responding appropriately to "no" are all within reach by 10 months for many babies. This does not mean they will reliably comply, but they often understand. The distinction between understanding language (receptive language) and producing it (expressive language) is important: comprehension typically runs ahead of production throughout the first two years.

Social and emotional development at 9 to 10 months is characterised by increasingly clear emotional expression. Babies show pleasure, frustration, excitement, and protest with distinct and recognisable signals. They hand objects to familiar people and expect them to be given back, which is an early form of social reciprocity. They look to caregivers for reassurance in uncertain situations, a behaviour called social referencing.

The 9 to 12 month health review

In the UK, a routine developmental review is offered between 9 and 12 months, typically carried out by a health visitor. This check covers physical growth and weight, developmental progress across motor, language, and social areas, hearing and vision, feeding, and any concerns the parent wants to raise. It is worth preparing a few notes beforehand about anything you have noticed or wondered about, since having them written down makes it easier to remember in the moment.

What comes next: 11 to 12 months

The final stretch of the first year brings first steps for many babies, consolidation of first words, and a diet that is beginning to look like a miniature version of family food. The first birthday also brings the 12-month vaccinations. Read more in Your baby at 11 to 12 months.

Frequently asked questions

What is cruising and when do babies start doing it?

Cruising is when a baby moves sideways along furniture, holding on with their hands for balance while their feet step in the same direction. It typically begins between 9 and 12 months, after a baby has learned to pull to stand. It is one of the key steps on the path to independent walking.

What is the pincer grasp and why does it matter?

The pincer grasp is the ability to pick up small objects using the index finger and thumb rather than the whole hand. It typically develops between 9 and 12 months and is important both as a fine motor milestone and because it enables babies to self-feed small pieces of food, which supports independence at mealtimes.

When do babies say their first word?

First intentional words, meaning sounds used consistently to refer to a specific person or thing, typically emerge between 9 and 14 months. The babbling that happens throughout months 6 to 10 is the developmental preparation for this. First words are often variations on mama, dada, or the name of a familiar object or pet.

What is a 9 to 12 month developmental review and what does it cover?

The 9 to 12 month review is a routine check offered by health visitors in the UK. It typically covers physical development and movement, speech and language progress, social and emotional development, hearing and vision, weight and growth, and feeding. It is also an opportunity for parents to raise any concerns they have.
