Little Sister Rainbow Onesie – Baby Short Sleeve Bodysuit with Heart Back
Size
Color

Soft, simple, and full of warmth, this cotton onesie wraps little ones in gentle comfort while celebrating sibling love. A hand-drawn pink-and-coral rainbow arches above playful hearts and the sweet script “little sister” on the chest, with a bold red heart centered on the back. Short sleeves and a lap shoulder neckline make dressing fuss-free, and the higher-front snap closure lets caregivers change diapers quickly without tugging. Lightweight and breathable, it wears like a second skin during cuddles, naps, and storytime.

This piece blends everyday ease with a sentimental touch. It slips into family photo sessions, newborn visits, or quiet afternoons at home. The clean white canvas keeps the artwork bright and the ribbed leg openings keep the fit snug as babies wriggle and grow. Thoughtful details — printed care label and Onesies® tag — keep distractions to a minimum so the design and the moment take center stage.
