Some prams come with integral brackets for a changing bag, but if you still want to hang your bag on the handle, there are different ways to do so.
One popular solution is to use separate pram hooks or choose a changing bag that includes them. These hooks attach to the handle with Velcro, making it quick and easy to attach and detach your bag.
Another option is to choose a changing bag with fixed attachments, such as a strap or hook on the bag itself. You simply pull the attachment around the handle and attach it to the bag, ensuring that it sits securely without sliding down while you're walking.
And if your bag doesn't have any special attachments for hanging it on a pram, don't worry. You can still hang it on the handle using the standard carrying strap - this works just as well with changing bags or ordinary handbags.
