Hey, Jurga,
Personally, I would probably look at non-reversible models at an age of about 1 year - especially if you would like to have longevity in mind. If money isn't the problem, then ok, and you may be ready to buy another stroller in about a year. If that is ok, perhaps I would still rather go for a pre-owned Thule Shine as that is truly quite some money (and environment) saved, and the stroller itself is a good one, sturdy-ish for that compactness. The Dragonfly is not bad of course, being new and shiny and fun, but I feel it's not that sturdy, and quite narrow in the seat, which is a price to pay for that extreme lightweightness.
