Ok ladies I am new to this forum but some of you may know me from diapering.... I have a DS who will be 3 in march and is a little on the small side for his age.... he weighs about 26lbs. Well we are going on a plane trip to see my family in may and I really dont want to bring his stroller. Now I do have several strollers that would be easy to take. I have a combi that is a full seat that lays back but folds like an umbrella stoller and i also have an inglsina swift. But he would rather be carried and i am also going to have a britax carseat to lug around. so what kind of back carrier would you reccomend for a 3 yr old that will be easy to get on quicky while getting off the plane?
