If your child's first word was "doggie" as he reached out to his best friend, dress him up in this sweet onesie featuring a smiling Rottweiler. It's soft, comfy, and made of 100% cotton (heather shades contain 10% polyester).. It's easy to put on and take off thanks to the flexible rib knit. It's available in sizes to fit infants from 3 months up to 2 years. Not suitable for sleeping. Since it's made of cotton, you can expect it to shrink by about one size if you machine-dry it. Makes a great shower gift for Rottie-loving parents-to-be, too!
