Newborn Sleep Gift Bundle - Mini Mathletes
The sleep essentials, matched and ready in one box — less to figure out for you, a complete setup for the baby.
Alligators on swings, elephants, kites, hopscotch — playground math.
It's the registry pick that arrives looking like someone meant it — three matched pieces in one print, boxed and ready to give, at 15% off the separate pieces.
The print. Cream ground with alligators on swings and seesaws, small elephants and pink bunnies, kites being flown by our Wolfie, hopscotch grids, balloons, small numbers, clouds, and trees.
Materials. TENCEL™ Lyocell on the sleeper. Tanboocel® Bamboo Viscose, blended with cotton on the sleep bag and swaddle. Both fibers are OEKO-TEX Standard 100 certified. The Lyocell is wood-pulp fiber Lenzing produces in a closed-loop process. The Tanboocel® is a branded Bamboo Viscose that's a step beyond generic bamboo viscose — third-party verified production with a lower water and chemical footprint.
Why it gives well. Three matched pieces in one print, boxed and ready — the registry gift that looks considered and actually gets used, not the fourth onesie in newborn size.
Adjacent products. Add a 1.0 TOG TENCEL™ Sleep Bag in Mini Mathletes for everyday 69–75°F nursery nights, or a matching muslin crib sheet to complete the registry set.
Sizing. Sleeper 0–3M / 3–6M / 6–9M. Sleep bag 0–6M / 6–18M. Swaddle is one-size at 47x47 inches.
Care. All pieces machine wash cold, tumble dry low. The Tanboocel® Bamboo Viscose softens through the first ten washes. The TENCEL™ holds its hand through multiple washes.
Safety & certification. AAP safe-sleep compliant. Tested to CPSC, CPSIA, and ASTM standards. Material certified to OEKO-TEX Standard 100. Loulou Lollipop is a Certified B Corporation.
Common questions
Why bundle instead of buying separately?
Two reasons. First, you save 15% on the set versus the individual pieces. Second, the pieces are designed to work together — a sleeper as the under-layer, a 1.0 TOG sleep bag for everyday nights, a 0.5 TOG for warm nights — so you don't end up with mismatched weights for the same room temperature.
What's the difference between the starter bundle and the gift bundle?
The starter bundle is built for the household using the pieces immediately — sleeper plus 1.0 TOG bag. The gift bundle adds a swaddle and a 0.5 TOG bag, packaged for the registry. Both include the same materials and certifications. The gift version is the one that arrives looking like someone thought about it.
Is the bundle returnable if the print doesn't match the nursery?
Yes — unworn, unwashed, in original packaging, within 30 days. The bundle is treated as one item for returns. Free returns on US orders.
Free US shipping over $65. Free 30-day returns on unworn items in original packaging.
