I hope someone can help me out. I’m currently trying to knit my friends baby a cardigan but I am stuck on the sleeves. I am following a pattern which basically looks like I don’t need to increase any stitches on the smaller baby sizes ( so like 0-3 months 0-6months etc) but I would have to on the older sizes. Is this typical? I’ve never knitted anything like this before. I’ve tried to put a picture on here but it keeps crashing. Any help would be greatly appreciated.
