Growing pains in toddlers can make bedtime difficult and ruin any good habits you’ve spent months putting in place. The key thing is that outside of affecting sleep, they’re not something you need to worry about. But even so, you’ll still want to alleviate any pains and aches your children feel. Read on for our guide on how to deal with growing pains in kids and ensure your child is getting the sleep they deserve.
Growing pains are cramp-like pains that occur at night in toddlers and pre-teens. They usually start around age 3 or 4 and can continue until age 12. As a child grows up, their body undergoes many changes – bones harden, and muscles develop. While growing pains in kids are most common in the legs, they can also be experienced in the arms and other areas of the body.
The most important factor is that these pains only occur at nighttime when the body is recovering from the day – so if your child is complaining of leg pain in the day, it’s recommended that you take them to a GP as soon as possible. The NHS also recommends Seeing a GP if growing pains are recurring, even if they only present at night.

"Growing pains aren’t caused by growth. They’re more likely due to muscle fatigue from an active day of running, jumping, and playing."
Surprisingly, no major evidence exists that growing pains are linked to growth. In fact, it’s still pretty much unknown what causes them exactly. Most science points towards the fact that they’re caused by intense muscle work throughout the day. For this reason, they’re more commonly experienced after your kids have had an active day. But even though the root cause is still unknown, there are ways to limit the pain, including massage, stretching, and fluid intake.
"There’s no evidence linking growing pains to growth spurts. It's more about activity levels."
One of the most common ways to soothe growing pains in kids is to gently massage the area affected. This is equally about showing them attention and helping them relax and get back to a state of sleep, as it is soothing their pain.
If your child has recurring growing pains, it’s worth getting them to stretch each night before bed. This doesn’t need to be extensive—some light stretches will have a great impact. By loosening the muscles, you can minimise any pain related to tension built up throughout the day.
As parents, we’re sure you’re aware that a little bit of magic can go a long way when it comes to soothing frustrated toddlers. So, a good tip is to use child-friendly moisturiser and tell them it’s a ‘magic cream’ that stops pain and helps them grow. You can also use a heating pad for a similar effect.
NHS guidelines state that you can give your child paracetamol or ibuprofen if pain persists. It’s recommended to use Calpol, as this contains a child’s dose of paracetamol. Netdoctor.co.uk states that you need to know the following before administering your child with Calpol.
"Gentle massage, stretching, warm baths, and sometimes over-the-counter pain relief may help to ease the discomfort, as well as some additional bedtime cuddles."
Despite their unknown cause, growing pains in toddlers and kids do not need to cause worry. They’re extremely common, with up to 20% of all children experiencing growing pains between the ages of 3 and 5 and 8 and 12, too. The most important thing to know about growing pains in kids is that they do not cause any long-term health effects. The only impact is the pain they feel at the time in question.
Despite growing pains in children not being a cause for worry, there are certain cases where toddler leg pain is not related to growth but something more serious. If you have any concerns, see your GP.
"Growing pains are normal muscle aches that happen in both legs in the evening. Despite the name, they're not actually caused by growing. If you're worried, make sure that you visit your doctor."
The following list is taken from the Palo Alto Medical Foundation (PAMF) and identifies symptoms unrelated to growing pains in toddlers and pre-teens. You must pay attention to these, as they could be signs of a more serious illness. The list is produced by Dr. Harris, who specialises in sports medicine at PAMF and has expertise in the care of child and adolescent athletes.
If your child has any symptoms outside of this list, it’s still important to see a GP if you have cause for concern. Your doctor will diagnose whether leg pain in children is growth-related or a sign of something else.
"Growing pains are evening aches that feel better by morning. If the pain persists during the day or affects just one leg, that's when you should call your doctor."
Growing pains are a normal part of development for many children and adolescents. Most commonly affecting people from 3-5 years of age and those between 8-12 years of age. They occur at night and feel like cramps or muscular pain. A gentle massage should normally help alleviate the pain, but in more severe cases, stretching before bed and using child-friendly painkillers can help. Be sure to check any medicine with your GP before use.
