Just wondering if anyone has this pram and has their toddler sitting in the seat over the front wheels? How is it to push with the greater weight over the wheels? I want to use it to walk so will be going up and down curbs also. Would this be difficult with the toddler at the front? We currently have a strider plus but have had issues with it so are thinking of getting the city select instead. I really like ds2 directly in front of me though and I'm not sure how that will work with the seat configuration on the pram. Thanks for your responses!
