A changing bag full of the absolutely necessary (clean nappies, creams, wet wipes, muslins, and a fresh set of clothes – or two depending on your child) should always be kept at the ready for your outings. There are as many styles as they are mothers. From basic, to over-the-shoulder, or from military and biker to absolutely chic. You choose and you pay. You should also invest in a waterproof cover to fit on to your toddler’s mattress if they are just out of trainer nappies. If you don’t mind having dirty nappies around for a while, you might also need a nappy disposal system, which is basically a container with a lid to store them in and you empty it when full.
