Riley loved to go for walks for his A time, loved to look at everything. It was a nice break from the house for me. Sometimes he did nap in there. If your lo has a good routine down and sleeps well in her crib, I don't think taking the odd nap there will upset everything. That is, if she will nap at all in her stroller, sometimes they get too busy and interested in their surroundings to sleep. And the catnap time is a good time to do naps while out and about.
