So are the prams. Expensive and usable for only a short period of time. If I'd known, I would have bought a pushchair which reclines fully and a newborn car seat separately. Now I am stuck with hardly used pram which cost in excess of €700. We haven't used in ages and I bought an 'umbrella' stroller in Tesco for €20.00 and have been using it for about a year now.
A big +1 to that. We have rarely used ours. The McClaren is the business though and is light and portable.
One thing you might consider too is getting a travel cot in case you're going anywhere over night. They fold up into a rectangular box and are light enough.
