Very pretty girl Richard
Yes make a nest and let her" find" it, somewhere warm and quiet,and have some clean blankets for mum and kitts,as you will need to keep kitts warm in between delivery's,for right now let her eat as much as she wants,raw red meat is great for expectant and nursing girls,complete dry food kitty bics,whatever she likes really and you probably don't get a choice anyway but lots of extra pampering
