I'm considering this combo for newborn (in a carrycot or bassinet) and DD, who'll be 2.8. I'm loath to buy a double because I don't think we'll get the use out of it, and I want the newborn to be comfortable and facing me. A buggyboard seems out of the question to me, for safety reasons. Although DD is a good walker, she does dawdle and we live a 30min walk from town, so we'll need something.
It looks like we could get a lot of use out of this combination - DD's current buggy is a Britax B-lite which is pretty hopeless really, so it would be nice for her to use the Baby Jogger as a pushchair for the time being. Obviously if we buy this, the baby will have the pram and then a pushchair, whereas if we bought a double we'd be replacing with another single after about 6 months.
Two things are holding me back: mixed reviews of the Smorph 2, and the fact that though it's compatible with the City Mini, it compromises the secondary brake. So, anyone tried it?
