Carrying a toddler on one hip hurts because of what your body has to do to hold them there. You push the carrying hip out sideways to make a ledge, then lean your upper body the opposite way to balance. That posture is often called a hip hitch, and it loads one side of your pelvis, your lower back and the muscles down the side of your hip. Do it for twenty minutes a day, on the same side, for two years, and it adds up. A hipseat carrier is designed to redistribute the child's weight through a wide padded waistband so you do not have to make that ledge with your own skeleton. It is not hands-free. One arm always supports the child.

What actually happens to your body in the one-hip carry?

Three things, all at once.

• Your hip juts out. To make a shelf for your child to sit on, you push one hip sideways and drop the opposite side of your pelvis.
• Your torso leans away. To stop yourself tipping over, you side-bend the other direction. Your spine ends up in a C shape.
• One arm does the holding. Your forearm, wrist and shoulder take the child's weight and keep them from sliding off.

Hold a 14kg toddler like that and the muscles down the side of your hip, your lower back and your shoulder are all working hard in a position they were not designed to hold for long. That is where the ache comes from.

Why is it always the same side?

Because you have a default, and you did not choose it consciously.

Most people carry on their non-dominant side so their dominant hand stays free for keys, phones, doors and coffee. That means the same hip, the same shoulder and the same lower back do the work every single time.

Add in the other habits stacked on that side, a nappy bag over the same shoulder, a toddler always in the same arm at the same time of day, and it becomes very one-sided very quickly.

What makes hip pain from carrying worse?

The usual suspects:

• Long carries. Twenty minutes at the shops is very different to two minutes at the front door.
• Always the same side. The single biggest driver of a one-sided ache.
• Carrying plus load. Toddler on one hip, nappy bag on the other shoulder, shopping in the free hand.
• A heavier child. The 15 to 20kg stretch is where most parents notice things start to hurt.
• Postpartum changes. Pelvic floor and abdominal recovery take time, and carrying loads that system.
• Existing conditions. Arthritis, hypermobility, previous pelvic or back injuries all change how much carrying your body tolerates.

What helps make carrying more comfortable?

Start with the free stuff.

• Swap sides deliberately. Not when it starts hurting, before. Pick a trigger, like every time you cross a road.
• Carry higher and closer. The further out from your body they sit, the harder your back works.
• Bend at the hips and knees to pick them up. Not at the waist with a twist, which is the classic way to tweak something.
• Put things down. If you can shed the bag, shed the bag. One load at a time.
• Shorten the carry. Break a long carry into two with a stop in the middle.
• Give the weight somewhere to go. This is where a hipseat comes in.

A hipseat like the HipSurfer sits on a wide padded waistband with a firm supportive seat. Your child sits on the seat rather than on your hip bone, so you are not hitching your pelvis out to make a ledge, and their weight is designed to spread across the waistband and both hips instead of loading one side. Your arm is still there, keeping them secure, but it is not doing all the lifting.

To be clear about what that means and does not mean: it helps reduce strain and makes carrying feel easier. It does not treat, fix or prevent anything. If you are already in pain, a carrier is a support, not a solution.

How is that different to a traditional carrier?

A traditional carrier spreads weight across your shoulders and waist and is excellent for long, uninterrupted carries. The trade-off is setup time and bulk, which is why most people will not put one on for a two minute carry.

A hipseat has no shoulder straps and goes on in around 15 seconds, which suits the stop-start rhythm of a toddler who wants up, then down, then up again. The trade-off is that one arm always stays on the child.

If your ache is mostly in your shoulders and upper back rather than your hip, our hip seat versus shoulder carrier comparison is worth a read. For the toddler up-and-down rhythm specifically, see our toddler carrier guide.

When should you get hip pain checked?

Book in with a GP, physio or women's health physio if:

• The pain sticks around when you are not carrying.
• It wakes you at night or gets worse over weeks.
• You have numbness, pins and needles or weakness in your leg.
• You have pain into the groin or pubic bone, particularly postpartum.
• It is not settling with rest and a bit of variety in how you carry.

This article is general information, not medical advice. A physio can look at your specific hips, and that is worth far more than anything you read online.

FAQs

Is carrying a toddler on one hip bad for you?

It is a normal thing to do and most people do it without issue. It becomes a problem when it is long, frequent and always on the same side, because that loads one side of your pelvis and back repeatedly.

Can a hip seat carrier help with hip pain from carrying?

A hipseat is designed to redistribute the child's weight through a padded waistband, which many parents find makes carrying feel easier on their hips and arms. It is not a medical device and does not treat pain. If you have ongoing pain, see a health professional.

Which side should I carry my toddler on?

Both, and more evenly than you probably do now. Deliberate swapping is the simplest change most people can make.

Is the HipSurfer hands-free?

No. One arm always supports the child. The seat carries their weight, your arm keeps them secure.

At what weight does carrying get hardest?

Most parents tell us it is the 15 to 20kg stretch, when the child is heavy but still wants to be carried constantly. The HipSurfer holds up to 25kg.

Does a hipseat change my posture?

It changes what your body has to do to hold the child. Because they sit on the seat rather than on your hip bone, you are not hitching your pelvis out to make a ledge. How you stand is still up to you.

Take some weight off that hip

If one side of your body is doing all the carrying, the HipSurfer is designed to spread the load.
