I've been meaning to post this for a while for those of us who are on the shorter side who think the Aeronaut is too big. I am 5'3". The Aeronaut and the baby weighed 20 lbs each. The Aeronaut carried everything for me and the baby, including diapers for a week, feeding supplies, and even a life vest! I walked a very long way through the airport (on both ends of the trip) with this setup and it was fine.
That is a black Side Effect under the baby with our passports and my wallet.
