In my experience, it does not matter what type of cool-modern-expensive pushchair you buy for the birth of your first child, most families end up owning a lightweight umbrella stroller.
They are great if you take them in and out of the car everyday, if you are traveling, or if you need to store them in a small place. Their most desirable feature, together with the light weight, is that they take up very little space once they are folded. Unfortunately they typically have very small shopping baskets (if any at all) which must be nearly empty once you fold it.
That is why I find this Stroller Organiser from Maclaren very useful — it gives you some place where to put essential items (bottles, keys & phone, a snack, a few nappies) and you don’t need to remove it when you fold the stroller.
It is made of sturdy neoprene, so it keeps its shape and dries quickly, and is super easy to attach thanks to some Velcro fasteners.
Needless to say, it will not hold a week-load of groceries but it can truly spare you from carrying a nappy bag, so you can sport your cute handbag instead.
Inexplicably it is available only in the US , Australia , Japan and a few other countries — but not in Europe.
