A.P.
I have a sit and stand stroller for my 2 kids. It works out wonderfully, because like you my daughter wants to walk, but after a long day she gets tired and wants to sit. I like it. It is a bit longer than a regular stroller, but not as big as a double stroller, so manuevering it takes just a little more work, but it's not too bad. The only downside on mine is that the storage basket under the seats is smaller than my regular stroller so I can't fit as much into it, and it is a little awkward reaching it...since the sitting bench is right there. I also wish I had a cup holder for me. But other than that it works out great.
