Seat Old

What is a good light stroller with a tall seat back for a 4 yr old?

I'm looking for a light stroller (umbrella fold preferably) with a tall seat back where a 4 yr old child can get good head support.
That is, full coverage, not where the seat back ends midway at the child's head.
Any suggestions or experience to share?

Thanks.
Edit:
Yes, 4 yr olds can walk but I was asking because they do get tired when you go to zoos, theme parks, etc.

Is there a medical reason (broken leg) or condition that your child has that requires you push them around in a stroller?

If so, you might need to look at medical supplies outlets to find something with a tall seat back to accomodate him/her. There are some groovy lightweight wheelchairs on the market (or available to hire) that don't necessarily look like the sort of institutionalised grey wheelchairs of old. They fold up really small for transportation, too.

However, if you just want a stroller for your average four year old, you might find it hard - I think the general perception is that by the time a child is four, they should be walking!
