So my ds is nearly two, not huge around average sized and I've had a silver cross surf, I candy raspberry and maclaren sold all the rest and only have the maclaren left but it feels really heavy now and ds is only 50th centile I was thinking of buying a bugaboo cameleon 2nd hand as I know it's still light to push with an older child but then I've just seen the oyster zero and was wondering what other pushchairs are light to push don't need parent facing really but something not to big but comfy with a decent seat im open to second hand any suggestions ?
