I told my wife our 5 month old was way too young for her own suitcase, but that didn't stop her from ordering this. However, it did come in handy on our recent trip. We didn't have to mix all of her baby clothes, toys and food in with our stuff and the 2 piece set allowed us to pack clothes and blankets in one and formula, bottles and pump parts in the smaller bag. Hopefully she will get plenty of use out of it over the next decade.
