Sometimes you need to duck out and it's not worth taking the whole nappy bag. But if you don't take a change, that's the brief moment your little gremlin will have a poonami, or you will get caught up longer than expected.
That's where nappy wallets come in. Take just enough for those in case situations.
These are a great size, will fit a full pack of wipes, multiple nappies and a change of clothes (smaller sizes of course, I have tested toddler clothes in it yet)
Also perfect to have in the car or bottom of the pram for those unexpected trips
