Hey Cora. Congrats on the new baby, that's such an exciting time, even if travel makes things a bit tricky with all the gear.
I get how frustrating a bulky stroller can be, especially when it gets stuck at the airport. After checking out those options, I'd suggest the Dream On Me Coast Rider Stroller because it's designed for easy travel with its lightweight build and one-hand fold that makes packing a breeze for planes or cars. It prioritizes safety and comfort for your 6-month-old too, and it fits right in your budget.
Some folks mention the storage basket is on the smaller side, but it still holds essentials well, and overall it's a reliable choice that should make your trips less stressful.
Good pick for portability but note the Coast Rider has a upright seat and limited recline, which can be tough for a 6-month-old on longer stretches. For under $200, the Summer 3Dlite or Kolcraft Cloud Plus are easier all-rounders with good recline and quick folds; the gb Pockit is ultra-compact for planes but bumpier and less cushy. Whatever you choose, practice the fold at home and lock the front wheels before collapsing to avoid that airport jam.
