My 2.4yr old son's travel pushchair (a Maclaren Triumph) is falling apart and we need to replace it. Was going to get another one the same but Maclaren site says maximum child weight for one is 33lbs and my boy weighs that now. Want umbrella-folding lightweight pushchair that will get quite a lot of use (my childcarer hates our big Jane Carrera that's our main pushchair so uses the Maclaren at the moment when she is looking after him) but want him to be safe - any recommendations for a good lightweight travel pushchair for a big guy?!!
