So I'm looking for a footmuff / nest / cocoon type thing for a newborn to go in a lie-flat seat, parent facing. She's due in August, so I'd rather not have sheepskin - I know it's supposed to keep them cool in hot weather, but I struggle to believe it. Everything else seems to be fleece - most of it polyester fleece, which I would hate to lie on in hot weather!. Does anyone know of a product that is lined in cotton - organic cotton would be even better! Am struggling to find anything. Nice colours or patterns would be a bonus!
