Baby joggers should leave room for a diaper and a good kick. Imps & Elfs has organic cotton pairs in solid colors and star prints, with sizes from newborn to 12 months across the options. The star-print joggers have an elastic waist and pockets at the side seams. This collection also holds baby leggings, Aimama pants, jeans and skirt leggings for bigger children. Don't choose baby pants by age alone. Compare the waist and leg length with a pair that fits over the diaper your baby wears, then check the product's available sizes.
