Infant Tee I'm a Big Boy Baby Shirt
Soft, light, and made to move with your little one — this infant tee brings a playful nod to growing up while keeping comfort front and center. The smooth, tightly spun fabric feels gentle against baby skin, while a ribbed collar and shoulder tape keep the shirt sitting right through crawling, hugging, and naps. Subtle side seams give structure so the shirt keeps its shape wash after wash. The cheerful “I’m a Big Boy” graphic adds a warm, confident grin to everyday outfits — layered under a cardigan, paired with shorts for sunny park days, or slipped on for milestone photos.
