My DD has only now started walking up to the shops and back - she is 3.5yrs. She will often walk for a while but get "tired" or she gets distracted. If she can't keep up or trips over she wants to get in the pram too. Other times I need to get somewhere in a hurry and she has to go in there.

She is now starting to get the hang of her bike so she might be able to use that but I don't trust her with roads etc (we live in a busy suburb).
