My son is just 3 and we take the pushchair a lot. He rarely goes in it, maybe right at the end of a walk - we live up a hill so he struggles!
But it's mainly so I dont have to carry things
we pushed it all around a theme park in the summer as a trolley, didnt one go in there.
That said, it probably is to make her life easier. I cant imagine her walks being anything less than perfect, slow, idyllic walks through the village
Mine consist of chasing my son and pulling him back from the road while I sweat my tits off!
