My little boy will soon be too big for his Uppababy Vista carrycot so I'm starting to look at what accessories I need for the pushchair. Is a footmuff necessary all year round or will a seat liner and blanket be enough for summer? The top of the Uppababy Ganoosh footmuff doesn't zip off fully - is this impractical or if I only intend to use it in cold weather does it not matter? Would I be better to get a universal footmuff which zips off fully? Does anyone have the new cozy Ganoosh and would you recommend it? It certainly looks better than the previous one. TIA
