Hello and welcome to the forum. Sorry I can't help with the curtains, I make all mine but have awful problems when it comes to pattern repeats. Is the fabric in a 'bricks and mortar shop' or online? If in a shop then I would ask the staff there as they should be able to tell you exactly what you need, if online then sorry I'm no good. Hopefully someone else will be along and be able to help. Congratulations on the little one.
