New baby sweater finishing

Hi, I have just completed an acrylic yarn sweater for my grandson who is 4 days old. Do I block it and how? And what do you suggest I wash it with?

I wouldn’t try to block an acrylic sweater–it won’t take. Just wash it on gentle with some baby soap–Dreft or Ivory–and dry it on low until it’s almost dry.
