I do quite a lot of walking with DD (3 months) and my current pushchair (Pliko Pramette, second hand) feels very rickety - I don't really like it. For any offroading it is really jiggly and hard to handle. So I was looking at three wheelers like the Jane Slalom Pro and the Mountain Buggy. But:
Are they so huge that they won't go through (fairly narrow) front doors?
Are they suitable for babies my DD's age to sleep in without forking out for an extra pram- bit?
Any other suggestions would be very welcome...
