A Blog For Mums
If your lovely little one has suddenly started doing the full crocodile-roll the moment they see a clean nappy, you’re not imagining it. Lots of babies start resisting nappy changes around 12 months, and it can feel like it came out of nowhere.
The good news is: in many cases, it’s a normal (and honestly very on-brand) part of development at this age. The slightly less good news is: you still have to change the nappy.
Let’s talk about why it happens, what usually helps, and when it’s a sign something else might be going on.
Around their first birthday, babies go through a big internal shift. They’re no longer just along for the ride. They’re becoming more aware of themselves, their bodies, and the world around them. Movement suddenly feels thrilling and important. Crawling faster, cruising furniture, climbing anything vaguely climbable, maybe even taking first steps. Staying still feels like a waste of valuable exploring time.
This is also when many babies start to understand routines. They recognise what happens next, even if they don’t like it. When they see the changing mat or the nappy coming out, they know exactly what’s about to happen. That anticipation alone can be enough to spark resistance before you’ve even unfastened anything.
At the same time, their understanding is running ahead of their emotional regulation. They can want things, dislike things, and express strong opinions, but they don’t yet have the skills to manage frustration calmly. So instead of mild annoyance, you get full-body protest. It looks dramatic, but it’s developmentally very normal.
Nappy changes are one of those moments where things are done to your child rather than with them. They’re placed on their back, asked to stay still, and handled in a way that doesn’t leave much room for choice. For a baby who’s just discovering autonomy, that can feel deeply uncomfortable.
There’s also a sensory side to it. Cold wipes, the feeling of being exposed, the noise of tabs being pulled open, the sudden change in position. For adults, it’s nothing. For a one-year-old with a nervous system still learning how to cope with sensation, it can feel overwhelming.
Some babies also learn very quickly that nappy changes get a big reaction. If every change involves chasing, coaxing, singing, negotiating, or gentle wrestling, it becomes a high-energy moment. That doesn’t mean you’ve caused the problem. It just means your baby has noticed that this is an interesting part of the day where a lot happens.
And sometimes, there’s a much simpler reason. If their skin is sore, they’ve got nappy rash, thrush, constipation, or they’re feeling unwell, being wiped or handled can genuinely hurt. In those cases, resistance is less about independence and more about self-protection.
One of the most helpful mindset shifts is moving away from trying to “win” the nappy change. If it turns into a battle of wills, everyone loses. Instead, small changes to how the change happens can make a big difference.
Involving your child often helps more than distracting them. Around this age, many babies love feeling useful. Letting them hold the clean nappy, pass you a wipe, or fiddle with the tabs can reduce resistance because it turns the moment into something shared rather than imposed. It doesn’t need to be neat or efficient. The goal isn’t perfection. It’s cooperation.
Predictability can also be calming. A simple running commentary, using the same words each time, helps some babies feel safer because they know what’s coming and when it will end. Even if they don’t understand every word, the familiar rhythm can take the edge off.
Confidence matters too. Hesitating, negotiating for too long, or apologising endlessly can sometimes make things harder. Calm, firm, and quick often works better than drawn-out reassurance. Acknowledging their feelings without stopping the process can look like, “I know you don’t like this. I’m going to do it quickly.” Then doing exactly that.
Changing the physical setup can help as well. Some babies hate lying down but cope better with a floor change or a standing change for wees. Others do better with pull-up style nappies because the change feels faster and less invasive. There’s no moral high ground here. Whatever makes it less stressful for both of you is valid.
While resistance is usually developmental, it’s worth paying attention to how your child reacts. If they seem genuinely distressed, cry when you wipe, or tense up in pain, it’s important to check their skin closely.
Nappy rash, thrush, or broken skin can make changes uncomfortable or painful. Constipation can also cause soreness around the bottom, making any contact unpleasant. In rarer cases, urinary tract infections can make wees sting, leading to distress during changes.
Trust your instincts here. You’re not overreacting by checking or asking for medical advice if something doesn’t feel right. Behaviour that comes from pain often looks different from frustration. It’s sharper, more sudden, and harder to soothe.
If your one-year-old is fighting nappy changes, it doesn’t mean you’ve done anything wrong. It doesn’t mean you’ve missed a parenting trick everyone else knows. It means you have a child who’s growing, learning, and discovering that they have opinions.
This phase often passes, especially as communication improves and routines settle again. In the meantime, a mix of involvement, predictability, and adjusting how you approach changes usually takes the edge off.
And on the days when it still feels like wrestling an angry octopus, you’re not failing. You’re parenting a very normal one-year-old.
