Speech and Language Milestones: A Practical Guide for Early Years Practitioners in the UK

Speech and language development is one of those areas where early years practitioners genuinely make a difference. Not because we're therapists (we're not), but because we're the people who spend hours with these children every day. We notice things. We hear the small voice that's not quite keeping up, the two-year-old who points but doesn't speak, the four-year-old whose words are there but nobody outside the setting can understand them.

The trouble is, there's a lot of noise around this topic. Parents get anxious, practitioners get unsure about what's typical and what isn't, and referral pathways vary wildly depending on where you are in the UK. This guide is meant to cut through some of that and give you something actually useful to work with.

What "typical" development actually looks like

The word "typical" is doing a lot of work here, because the range of normal development is genuinely wide. Two children born in the same month can look very different at 18 months and both be absolutely fine. That said, there are patterns most children follow, and knowing them well helps you spot when something feels off.

By 12 months, most babies are babbling with real intent: changing pitch, making eye contact while they do it, responding to their name consistently. They're not just making noise for the sake of it. They're communicating. Even if they don't have words yet, a 12-month-old who babbles back at you when you talk to them, who uses gestures like waving or pointing, is showing you their communication system is building well.

Around 18 months is where practitioners often first start noticing gaps. The general expectation is around 10 to 20 words at this stage, but more importantly, the child should be using words with intention. "Mum" called out across a room, "no" said with conviction, "more" at the snack table. Functional language matters more than the raw count. I've worked with an 18-month-old who had three words but used them consistently and meaningfully, and another who could repeat almost anything but wasn't using language to communicate at all. The second child needed support far more urgently.

By age two, most children have around 50 words and are starting to put two words together: "big dog", "daddy gone", "more juice". The vocabulary explosion that typically happens between 18 months and 2 years is remarkable to watch. Children who aren't experiencing it stand out. That's not cause for panic, but it is cause for closer attention and, usually, earlier referral rather than later.

Between two and three, sentences get longer and grammar starts to appear. Not perfectly, but noticeably. "I want the red one." "Where doggy gone?" By three, most children can hold a basic conversation, answer simple questions, and be understood by unfamiliar adults around 75% of the time. The 75% figure comes up a lot in speech and language resources and it's a useful one to keep in your head.

At four and five, children should be mostly intelligible to strangers, able to tell a simple story with a beginning and end, use questions accurately, and follow multi-step instructions. The EYFS expects children to be "using language well" by the end of reception, and while the framework doesn't spell out what that looks like in clinical terms, Development Matters gives you a reasonable picture of expected progression through the early years.

Red flags worth knowing

No response to their name by 12 months. This is one of the clearest early indicators that something needs checking out. It doesn't automatically mean anything specific, but it's not something to wait on.

Loss of skills is always significant. If a child was babbling or using a few words and then stops, that needs to be flagged promptly. Regression without a clear cause (like a new sibling, a house move, a bereavement) should be taken seriously.

Frustration and behaviour that seems linked to communication is worth noting carefully in your observations. I've seen children labelled as having "challenging behaviour" who were actually deeply frustrated because they couldn't make themselves understood. Getting speech and language support in those cases transformed the behaviour picture as well. If you're writing a SEND support plan for a child with communication difficulties, documenting that connection between unmet communication needs and behaviour is really important.

Persistent stuttering beyond the age of five, or a stutter that is causing real distress at any age, should be referred. Some dysfluency between two and four is very common and usually resolves on its own. But if it's affecting the child's willingness to speak, or if it's been going on for more than six months, don't wait.

Unclear speech that isn't improving. Some sounds come in later than others (the "r" sound, for instance, often isn't fully established until age six or seven), but if a child's speech is consistently difficult to understand and other children the same age are much clearer, that's worth getting assessed.

What you can do in the setting

The most effective thing most practitioners can do is also the simplest: talk to children. Not in the performative, question-and-answer style that's easy to fall into, but in genuine, back-and-forth conversation. Ask questions you don't know the answer to. Follow their lead. Comment on what they're doing rather than quizzing them. "Oh, you've put all the red ones together" is more useful than "What colour is that?"

Running commentary is particularly good for younger children and those with delayed language. When you narrate what's happening in simple, clear language, you're giving children a model without putting pressure on them to respond. "We're washing our hands. Water on. Soap on. Rub rub rub." It sounds a bit odd at first but it becomes second nature quickly.

Books matter enormously. Not just reading them, but talking about the pictures, making the voices, letting children interrupt and comment. In my experience, children who have regular, unhurried book time with an adult who genuinely engages with them make faster language progress than those who just sit through a group story. That's not a research paper, it's just what I've observed over many years.

Singing is underrated. Songs and rhymes build phonological awareness, which is the precursor to reading and spelling, and they give children a low-pressure way to practise speech sounds. The repetition is the point. "Twinkle Twinkle" sung every single day is far more useful than a different song each time.

Reduce background noise where you can. Open-plan settings with lots of children are genuinely difficult acoustic environments. Children learning language need to hear it clearly. Some settings I've visited have been so noisy that I've struggled to hear what adults were saying to me, let alone imagine what it was like for a child just starting to tune into speech sounds.

When you're planning activities across the seven areas of learning, it's worth making sure communication and language isn't just appearing in timetabled "literacy" moments. It should be running through everything: the outdoor session, the maths activity, the creative play. Children don't switch off language development because the session is about counting.

Referring on: when and how

Too many children wait too long. I think the culture of "let's give it a bit more time" has done real harm in some cases, particularly because NHS speech and language therapy waiting lists are long in many areas. By the time a child gets to the top of the list after a referral at two and a half, they might be four. Starting that referral process earlier, even if it feels premature, is often the right call.

Most areas allow practitioners to make direct referrals to NHS SALT services, though the process varies. It's worth knowing your local pathway, including whether there's a community paediatrician or health visitor who needs to be involved. Some areas use an early years SENCO referral route; others go direct. If you're not sure, your area's Early Years SENCO or the health visiting team should be able to tell you.

Before referring, document what you've observed. Specific examples are much more useful than vague descriptions. "Jake doesn't talk much" is less helpful than "Jake uses around 10 single words consistently but has not been observed putting two words together in the three months since he started with us. He communicates primarily through pointing and pulling adults by the hand." That kind of detail helps the SALT team understand the child before they even meet them.

Parents need to be part of this conversation from the start, not brought in at the point of referral. Most parents whose children are referred for speech and language support have already noticed something, even if they haven't put it into words. Talking openly and non-alarmingly is a skill worth developing. Lead with what you've noticed, explain why you think an assessment would be helpful, and make clear that early support is positive, not a verdict on the child or the family.

There are some useful external resources worth knowing. The Communication Trust has good practitioner materials. I CAN (now part of Speech and Language UK) produces accessible guidance for both practitioners and families. The Elklan courses are excellent if you want more structured training, and many local authorities fund early years staff to complete them.

One practical step that works well is setting up a "communication friendly spaces" check in your room. Anni McTavish's work on this is accessible and genuinely useful, and it gives you a structured way to audit your environment and your practice.

When you're writing end-of-term reports or progress summaries, being precise about communication and language is worth the extra effort. Vague comments like "X is developing their language skills" don't give parents useful information and they don't help the child's next setting either. If you want guidance on making reports more meaningful across the board, the advice in writing meaningful end-of-term reports applies to communication observations just as much as anything else.

The honest takeaway from all of this is that your instinct matters. If something feels like it's not quite right with a child's communication, take that seriously. Document it, talk to the family, look at your referral options. You don't need to be certain, and you don't need to wait until it's obvious. Getting a child seen by a speech and language therapist who turns out to be developing typically is not a failure. Waiting too long to refer one who needed support is a much bigger problem.
