From hospital coming-home announcements in Dallas and Toronto to crisp autumn pram walks in London, Dublin, Melbourne, and Auckland, one heirloom piece turns every baby milestone photo into a frame-worthy memory: a chunky cotton pullover hand-stitched across the chest with your child’s name. In the United States and Canada, parents search for a personalized chunky knit baby name sweater; in the UK, Ireland, Australia, and New Zealand, families call it a personalised knitted baby jumper.
In this complete sizing and styling guide from our studio at Bloom Blankets (operated by RIOXCORP LLC), we break down exact inch and centimeter measurements from Newborn (0–3M) through Toddler (3–4Y), name-length tips, and how to bundle a sweater with an embroidered blanket to unlock Free Shipping.

Turn your knitted baby jumper inside out, slip it into a zippered mesh laundry bag, and machine wash cold on a gentle cycle (max 30°C / 86°F) with mild baby detergent. Gently press out excess water in a towel, reshape flat, and air dry away from direct heat.
