Your baby at 12 months: development milestones & what to expect
8 min
Happy birthday, little one! And happy birthday to you – the anniversary of what was probably one of the biggest days of your life. You deserve a special celebration all of your own, for making it to this milestone.
What a wonder this last 12 months has been. A year of long days, longer nights, and months that pass by in a flash. But here you are, your little one’s first birthday – the first of many. You’ve done a fantastic job and should be so proud of yourself and your little family unit for all you have achieved. Let’s see what else you’ll be celebrating.
Physical development milestones at 12 months
Your little one may well take their first steps this month, if they haven’t already started walking. Some babies seem on the brink for a long time before they have the confidence to take that first step, instead relying on their parents for stability. Give them the space and independence to try and fail – a few falls are to be expected while they’re still learning.
The other rapid development around this age is speech. You might still be waiting for that special first word, but once they get started a second word tends to follow relatively quickly and soon they will have a small collection! Even their babble is relatively understandable these days, with the cadence and intonation of real speech. It’s fun to chat away with them and pretend you’re having a good ol’ gossip.
Hand-eye coordination continues to improve as they get more practice through play and mealtimes. Your little one should be able to manage an open cup soon, but expect plenty of spillages while they get used to it. You might prefer a sippy cup with a lid. More on that later.
Milestone checklist
- Practicing – Your little one is pretty determined. They’ll keep practicing cruising and walking until they get the hang of it.
- Copying – Even if your baby hasn’t got any words yet, they will mimic the sound of your voice, copying the cadence of a conversation so well you could almost believe they know what they’re saying.
- Eating – Your little one is getting more of an appetite and expanding their list of comfort foods. By now, they might be able to manage a spoon by themselves.
Child brain development at 12 months
Play time is school time when you’re 12 months old. Everything you learn, you learn through play and observation – watching your big brother kick a ball, the shape of your mother’s mouth when she says your name, the particular problem-solving that occurs when finding something that’s been hidden from you. The whole world is an education.
But your baby is still very young and all this stimulation can be exhausting. So don’t be surprised if your little one seems emotional – there’s a lot going on! Those long afternoon naps are an important opportunity for a rest and reset to give them the stamina to keep going through dinner.
If you’re thinking about what type of toy to buy them for a birthday present, you can’t go wrong with shape sorters at this age. At 12 months, your baby is getting good at putting objects in and out of containers. Working out which shape goes where provides plenty of stimulating entertainment. Similarly, a home-made box of sensory toys would also go down a treat – pulling a long scarf from a small hole is plenty of fun, and you could also hide other kinds of textured materials for them to find. Just be careful that it’s all safe to put in their mouths, as that’s almost certainly where it will end up!
Social & Emotional Development
Your 12-month-old is still likely to be clingy right now, and may well cry when you leave the room. Try not to be frustrated – they just don’t yet understand this whole leaving and returning thing. That only comes with plenty of practice, so in fact you leaving and coming back is a helpful lesson.
Try to be positive at both ends of this interaction. Babies pick up on your stress, so even if you don’t feel happy leaving them – for example at nursery or with family – put on a smile. It’s fine to stay with them for a little while to help them settle in a new place, but don’t spend ages trying to make them understand why leaving is necessary. They’re not developmentally capable of that kind of understanding yet. Keep your goodbye short and sweet, if you can, and save up lots of hugs, kisses and praise for when you’re reunited.
Sleep & Feeding
Rhythms and routines at this stage
From 12 months old, you can start to introduce two daily snacks to the menu, which means your days might be starting to feel a bit hectic. Wake up – milk – breakfast – nap – lunch – milk – nap – dinner – milk – bed was hard enough. Where are these snacks meant to fit in?
Gradually that morning nap might get shorter, and you might find there’s a long wake window in there where a snack becomes necessary to get your little one through to lunch. And now that meals are bigger, you might take out that post-lunch milk feed and instead have a post-nap, pre-dinner snack. The schedule is up to you, and you might have to play with it a bit to see what works.
Sippy cups
As you start phasing out milk, you might also be phasing out the bottle. The NHS recommends that you phase out bottles once your little one turns one, for the sake of their teeth. But the NHS is not dealing with a hangry toddler who wants their milk. The best advice for this transition is to start making it at mealtimes.
Try to get your baby comfortable with drinking – water or cows’ milk – from either an open cup or a cup with a lid while they’re eating. They might be more likely to cooperate if they see that their cup is not that different to yours.
The key with the lidded cups is that you want something that’s free-flowing, not a straw or spout they have to suck through – otherwise they may as well still be using a bottle. Free flowing cups are any that require you to tip the cup up to work – which means, as previously mentioned, spillages are likely. But your baby will soon get the hang of it. An alternative to the lidded cup, if you’re feeling brave but want to give your baby a bit of a leg up, is the doidy cup, which is slanted to help your little one see the liquid as they tip the cup, making it easier to coordinate their hands and mouths.
What’s a good snack for a 12-month-old?
If you struggle to think of healthy snacks, you’re not alone. It’s too easy to reach for the biscuit tin! But we’re trying to teach our little ones to do better, so let’s consider some healthy snacking options for your 1-year-old.
- Sliced fresh fruits or soft veg – easy to pack in Tupperware and take anywhere
- Banana – the old faithful!
- Finger sandwiches – a little pre-lunch lunch
- Oat cakes – the more nutritious offer compared to rice cakes
- Homemade biscuits and cakes – if you enjoy baking, look for no- or low-sugar recipes so you can control what your little one is eating
- Breadsticks and hummus – delicious, and perfect for sharing if you don’t mind double-dipped soggy breadsticks
Appointments around this time
It’s your next round of vaccinations this month – perhaps not the birthday present your little one was hoping for! Included are:
- MMRV (1st dose) – Children born on or after 1 January 2025 are given their first dose of the MMRV vaccination at 12 months. (The second dose follows at 18 months). MMRV replaces the MMR vaccine and helps protect your little one against measles, mumps, rubella and chicken pox.
- Pneumococcal (2nd dose) – The pneumococcal vaccine was first given to your baby at 16 weeks and this is the second dose. It helps protect against some types of bacterial infections, including sepsis, meningitis and pneumonia.
- MenB (3rd dose) – The MenB vaccine was given to your baby at 8 weeks and 12 weeks, so this marks the third dose. It helps protect children against bacterial infections caused by meningococcal group B bacteria.
Your little one might be more aware of what’s going on this time, which can be very hard. The good news is they’re also more distractible, so try and go prepared with your partner or another helping hand to provide ‘entertainment’ and additional comfort and praise after the event. Your healthcare practitioner will advise what pain/fever relief might be necessary, so stock up on infant paracetamol ahead of time.
Also around this time, you’ll meet with your health visitor for your baby’s 9-12 month review, as covered in last month’s update. For both vaccinations and the health visitor, don’t hesitate to chase your GP surgery if you haven’t been offered an appointment. It’s best to get it in on time, if you can.
Looking after yourself
If you’re heading back to work this month, go especially easy on yourself. This is a huge transition and marks the beginning of the real juggle between work and family. Remember that you’re not starting from scratch – you are an asset to the team, and you’ve earned your role. Having a baby hasn’t affected your ability to do your job; if anything, you have spent the last year levelling-up your productivity.
That being said, the workplace can be a difficult place for mothers – especially when your little one is just starting nursery and picking up every bug under the sun. Here are a few reminders of your rights as a parent:
- If you’re still breastfeeding, you have the same health and safety rights at work as you did while pregnant. You also have the right to a private space to express milk.
- You have the right to emergency unpaid leave to care for a dependent – for example, if your childcare arrangements fall through.
- You have the right to take unpaid leave for childcare – usually in weeks rather than days, though check with your employer on their rules of entitlement.
If you’re having a dispute with your employer over your caring responsibilities, it’s worth talking to Citizens Advice for free advice and support. And of course, you’re not the only one who can take care of your baby. If your partner is not newly returned to work, they might be best placed to handle emergencies until you’ve settled back in.
A Note on Development Milestones
Developmental milestones are guides – not deadlines. If your baby isn’t ‘keeping up’ with your friends’ babies, it isn’t an immediate cause for concern. Every child develops at their own pace. That being said, your health visitor and GP are there to support you with any queries you might have and will always be happy to see you with your baby if you have any worries.
