The SW is hands down the best baby related purchase I ever made! It's handy for those quick trips when a pram is too much effort to get in and out of the car. It can take a few goes to tie it at first but once you get the hang of it, it's great. I put mine on before I go out and then all i have to do is pop DS in when we get there. People always comment on it when I'm out and about..they reckon DS looks very comfy!
