I do not think baby quilts, blankets or afghans will ever go out of style.
I live in a rain forest climate and in the winter we get lots of rain, plus the ground can be damp, except during the dry summer.
I made a blanket (not a quilt) for a friend who teaches stroller fit classes to new mums. I used minkee on one side and pul (Babyville waterproof diaper cover) on the other. It was warm, waterproof, and can be used on the ground on warm days.
Baby will need a covering for the car seat, stroller, even as an extra covering when in a baby carrier. As well as when held, for floor play etc.
