We have DD1 3.5 and DD2 13 months.
DD1 has some mobility problems (very mild CP) and gets tired easily when walking, so needs the option to go in a buggy. She also still needs to nap sometimes and naps best in the buggy.
At the moment we have a Phil and Teds Navigator and she goes in the front. She fits in the seat but her legs are a bit long for it - if she is asleep her feet will hang down and rub against the front wheel. She is tall ish (75th centile) and has disproportionately long legs!
I was hoping she would stop needing the buggy before she outgrew the P&T but I don't think that's going to happen. I can see that within a few months she will be too big and I think she will still need it come September.
Are there any inline doubles which have more leg space for the older child? And ideally a slight recline? Realise this is a pretty niche request...
