DS is 13 months and we use the Ergo all the time. It's great! I wouldn't be comfortable with him walking around on his own yet and sometimes bringing the stroller is impossible or a hassle.

How long do you think I can use the Ergo for? I'm thinking of things we'll do this spring, taking DS on the subway, etc. Is that realistic with the Ergo? I can't imagine lugging around the stroller.
