Hi there, I get what your saying, I had the Cameleon for my second child and it cost over £1000 inc all the accessories (footmuff, buggy board etc) as you say it is pretty expensive! We've travelled round Europe a lot and the bugaboo is very popular, I've seen people with buggy chains (pretty similar or the same as bike chains) attached to their Bugaboo outside Cafes, Restaurants and Parks, so that's always an idea. Tbh I didn't invest in one as I made sure my pram was always beside me and bought a MacLaren for times where I knew I couldn't take the buggy in (toddler classes etc). Look at it this way, would you leave £1000.00 sitting about? No way! So I think your wise to ask! They are very expensive & popular push chairs. Good luck with your decision. They are by far worth every penny, quality and hard wearing prams.
My eldest is 5 so I've got a few pushchair years under my belt. I can count on one hand the number of times I've had to leave the pushchair somewhere. Usually it's right beside me. I have heard of pushchairs being stolen and every single time it's been from the owner's front porch.
We used it with DD from birth with no probs - she was in the carry cot for the first couple of months, then the car seat, then when I was ready for her she was ready to face forwards she sat in it as a normal pram.
