Hi there-I bought the Urban Detour with the car seat from birth and also the carry cot so little one could sleep flat in it. My lo is now 21 months and I would not recommend the Urban Detour. Reason being, the harness has recently broken on the pram and I called up Mothercare to ask about purchasing a replacement, only to be told that it would cost me at least £40-£60 as the harness is attached to the actual board of the pram. They also said that the board would most likely be a different colour as the fabrics change all the time. Very disappointed.
