Baby Sleepsuit 1.0 TOG in TENCEL™ - Smiley Sharks

Hands covered, warmth without overheating — the all-in-one that keeps a baby settled from the first yawn to morning.

Smiling sharks and little fish — the friendly version of the shark phase.

It's built for the 6–18M stretch, when the baby has outgrown the swaddle, wants their arms free, but still kicks off every blanket. The sleeveless cut frees the arms while the closed legs keep the warmth where it belongs, rated for a 69–75°F nursery.

Material. TENCEL™ Lyocell with a touch of spandex for stretch. TENCEL™ is the wood-pulp fibre Lenzing spins in a closed-loop process that recycles 99% of its water and solvents, certified to OEKO-TEX Standard 100. It's softer than cotton and keeps its shape through heavy washing — the pajamas your baby still has at 18 months are TENCEL™.

Why a sleepsuit. Between 6 and 18 months the baby has outgrown the swaddle, wants their arms free, but still kicks off every blanket. A sleeveless suit with closed legs is the answer — arms loose, warmth kept where it belongs.

The print. Cream-ivory ground (navy binding) with watercolor smiling sharks — great white, whale, hammerhead, and tiger — in white, gray, and blue tones, with small fish and blue stars.

Construction. Sleeveless and footed-free — arms loose to move, body covered to stay warm. A two-way zipper opens from the bottom for fast changes, the neckline is tagless, and the seams are reinforced at the stress points.

When to switch from sleep bag to sleepsuit. Most families switch around 12–15 months, when the baby is walking confidently in the crib. The closed-leg sleep bag becomes a trip hazard at that point. The sleepsuit gives the same TOG warmth with mobility. Some families switch earlier if the baby protests the closed-leg bag; others stay in sleep bags longer if the baby is content.

Sizing. 6–18M, 18–24M, 2T. Size to current weight and height.

Care. Machine wash cold and tumble dry low. Don't bleach, and don't iron the printed areas. TENCEL™ holds its surface through the two or three washes a week a baby's laundry demands.

Safety & certification. AAP safe-sleep compliant and tested to CPSC, CPSIA, and ASTM standards. The material is certified to OEKO-TEX Standard 100, and Loulou Lollipop is a Certified B Corporation.
