I've used a lot of brands of prams for the earlier stages (borrowed when we were travelling, I haven't even bought a single pram other than a light pushchair) and I have to say bugaboo are the lightests and easier to maneuver for that type. I've only had the chameleon and the bee though of their range. But I'm assuming you know based on your wording lol.
My bugaboo is in bits. It belong to my soon to be 14 year old nephew and this would be the 5th baby using it so I'm thinking of buying one.. maybe the yo-yo +. Still considering.
If you think that's crazy. My SIL bought a quinny for her first, then decided it was too heavy and a few weeks later she put it away and bought the bugaboo. Then one day she decided the boot of her car made it too awkward and she didn't want to be folding the pram every time. So she drove herself to the nearest dealership with the bugaboo in hand. Started opening boots and trying which car would take the pram as is... She settles for a vw Tuareg, ordered it there and the (without looking at anything else, test driving or even telling her husband)
