hi, I'm expecting nr 2 and come April I'll have a 2 yr old and a newborn. i don't want a double buggy as it wouldn't fit into our hallway (firstfloor/ small London flat) been looking at PhilandTeds E3 which is a single that can upgrade w toddler seat, but feel reluctant as the second child is very low to the ground. Does anyone have experience with these? I've also looked at ABC a new NZ made which is expensive but looks like it'll last me the next 4 yrs which is a big plus, just worried that child nr two wont be able to kip. Oh all these worries, does anyone have experience w good slim/ lightweight 3 wheeler (or even 4) that can fit 2 kids? thanks mir
