Hi we are going on holiday in November and need a stroller. I have had the yo-yo zen recommended to me by lots of people and although it is expensive I think that is what we want. My daughter will turn 5 months when we are on holiday. They say you should buy a newborn pack for babies up to six months. This is an extra 190 pounds for something she will use once on this holiday. It also looks rather hot and we are taking her to Dubai. Has anyone used it without the baby pack for a five month old or do we really need it?
