Bub No2 is due in November when DS will be 2 and 2mths. I don't really use his current buggy masses - usually travel by car. The most we use it for is about an hour or so when we have to go into town. DS will walk, but only for a bit before it's "Cuggle, cuggle", meaning "I'm tired of walking now, can you carry me" - this is when he goes back in the buggy! Anyway, question is, what kind of double buggy should we get? Pros and cons of tandem or side by side please. We have about 150 max to spend...
