My DH and I have had the idea that it would be nice to go to the Lake District for a few days with DD (she's 14 months), which would include a fair amount of walking. We like the idea of one of those backpack baby carriers to put DD in as a pushchair would be pretty cumbersome and she loves being carried by daddy! But they are pretty expensive and I don't know if we'd get that much use out of it, anyone got one, and what do you reckon?
