"Toddler" and "shopping" are two words that are likely to instill instant fear into the heart of all but the most unflappable of parents.

There are perhaps few less relaxing tasks than navigating the shops while lugging a young child who would rather be playing, running around — anything, in fact, other than sitting in a buggy watching their mother ponder which brand of tofu or what color bath towels to buy.

Grown-ups often simply want to shop quickly and efficiently, but toddlers tend to have another idea in mind: They would much rather free themselves from their buggy, David Copperfield style, before emptying the contents of shelves onto the floor or showing off their window-shattering vocal abilities by having a tantrum.
