Joovy Caboose

Our children are 18 months apart, and when our son was tiny it was easy - we used our existing buggy and a sling. However, he got too big for that and my daughter wasn't big enough yet to walk everywhere so a double buggy was clearly needed. I did a lot of research and read a lot of reviews. The things that put me off were either a huge footprint (length or widthways) or a 'double-decker' arrangement where one child is basically underneath the other. These latter types also seemed to be grown out of pretty fast, not to mention being very expensive.
Then I stumbled across the Joovy Caboose. You can only buy the Ultralight version in this country, from Mothercare, but I hate Mothercare so I emailed Joovy in America to ask if they shipped direct. I got my Joovy caboose for £180 including shipping from the US, when the version Mothercare sell is £280.
So how is it? The idea is that your toddler stands on the step at the back or, if tired, turns around and sits down. The baby goes on the front in a carseat and then in the seat. It's solidly built, and steers well because the heavier child is closer to you. The full-width steering bar also means that it's easy to push with one hand. The carseat adaptor is universal and comes with the buggy. The buggy collapses easily and has the footprint of a single buggy - it's about the same weight, too. The front seat has a footrest that sticks straight out, so even when your smaller child is very small its legs are supported. My toddler loves it, and it's great for her to have the flexibility to ride looking forward or to sit on it. It's a lot easier to persuade her to get back in/ on after a trip out, too!
Downsides - of course any double buggy has compromises. If you're using the carseat up front then your toddler doesn't have much room to sit down. The rear seat also doesn't have a backrest so it's no good at all if your toddler likes to nap in the buggy. Mine doesn't, so it's not a problem, and she doesn't seem to mind the lack of something to lean against (always sits bolt upright anyway) but I can see that some people would find it a put off.
Overall I think the design, build quality and low cost (relatively speaking) make it a winner - I'm certainly very happy with it and I wouldn't exchange it!
