Crochet baby pants pattern for beginners; designed by Paige Fritsche at Paige In A Blanket on Etsy. These baby bottoms can be crocheted into shorts or pants. The pattern includes instructions for three different sizes; small, medium and large. Generally, small is for a newborn, medium is 6-12 months and large is 12 months to 2 years. The bottoms will start by fitting loosely and as the baby grows the crochet will stretch with them. An elastic waistband helps the pants grow with the baby.
