I have an Oyster 3, which has a five point harness where all the parts plug in to a central, circular button which you push to release. I think this is the standard kind of fastening.
However, today my button-loving 2 year old managed to undo the harness himself and since I was behind him I didn't notice, and he ended up falling out of the buggy. Luckily it was onto soft grass but I'm terrified to think it could just as easily have been into the road.
I've been thinking about getting a more lightweight buggy for a while now as the Oyster is fairly clunky, and I have another baby due in April so will want to use the Oyster with the carrycot for him then anyway.
So I'm wondering if a lightweight buggy exists with a more secure kind of harness than a button which releases everything. The Chicco ones seem to have buckles which look good, but some of the reviews say they are a bit flimsy. Does anyone know of any others?
