My bag is currently a medium sized black snakeskin effect one from New Look. I can be guarantee to have anything I will ever need in my bag at any one time because I carry EVERYTHING around with me!
throat sweets, tablets, pill, tissues
car and flat keys
mini dry shampoo
purse with cards and ID
I also have Cameron's Changing bag which contains:
his special cream
a bowl and spoon
a cool bag with at least one bottle ready with water in
a container with enough formula to make up the bottles I have with me
So as you can see, I like to always be prepared!
