I understand that you point out single to double models for people who probably want more children. But actually if you have your children close in age, I think it makes more sense to have a side-by-side double pushchair. They are so much easier to manage than tandem pushchairs and the doorway issue is overrated. Side-by-side models are made to still fit through standard doorways. So I think once I have two children I would like to buy the Out'nabout Nipper Double. I know it doesn't have reversable seats, but I think when you have two children the youngest one is probably fine being next to the other child. And when I have my first child I really like the iCandy Lime. I do want the carrycot and I do want the reversable seat. And this one is still quite compactly folded even with all of that.
