I have a friend expecting her third child who is looking at twin buggy options as there'll only be 20 months between her second and third children. She wants a side by side 3 wheeler and so far has only seen the Mountain Buggy one, which is very expensive. I've seen oeople out and about with an XTS version, which looks good, and others have told me they didn't get on well with the Mothercare version, but there must be others out there. Can anyone offer advice on what there is on the market and relative pros and cons?
