Baby Sleep Essentials & Bedding

Shop baby sleep essentials and bedding, including sleep bags, sleepers, pajamas, swaddles, crib sheets and muslin quilts, thoughtfully designed for newborns, babies and toddlers.

Baby Sleep Essentials for Every Stage

From the newborn months through the toddler years, sleepwear and bedding needs change as your little one grows. Loulou Lollipop brings together baby sleep bags and sleep sacks, sleepers, pajamas, swaddles, crib sheets and muslin quilts so parents can find practical bedtime essentials for different stages and seasons.

For newborns, swaddles and one-piece sleepers can be part of a simple bedtime routine when used according to current safe-sleep guidance. As babies grow and transition out of swaddling, an appropriately sized baby sleep sack or sleep bag can provide a wearable layer for sleep. Older babies and toddlers can move into different sleep sack sizes, sleepers and pajamas based on their size, room conditions and bedtime routine.

Use each product's sizing, material and care information to choose an option suited to your child's current stage rather than relying on age alone.

How to Choose Baby Sleepwear & Bedding

Choosing baby sleepwear and bedding starts with four practical factors: your child's developmental stage, size, room temperature and the product's intended use.

For sleep bags and sleep sacks, check both the size and TOG rating. TOG indicates the product's level of thermal insulation, so different ratings are suited to different conditions. What your baby wears underneath should also be considered alongside room temperature and the guidance provided for that specific product.

For sleepers and pajamas, look for a comfortable fit that allows natural movement and check the product's size chart before ordering. For nursery bedding, choose products specifically intended for their stated use and follow current safe-sleep recommendations when setting up your baby's sleep space.

Baby Sleepwear & Bedding Materials

Material can influence the feel, weight and everyday practicality of baby sleepwear and bedding. Loulou Lollipop uses materials including TENCEL™ Lyocell and Tanboocel® across selected baby and children's products.

TENCEL™ Lyocell is used in selected sleepwear and sleep bag styles, while muslin is a lightweight and versatile material found in products such as swaddles and quilts. Because materials and fabric compositions vary between products, check the individual product page for exact material, care, sizing and TOG information before making your choice.

Baby Sleep Essentials FAQs

What baby sleep essentials do I need?

Common baby sleep essentials include appropriately sized sleepwear, a fitted crib sheet and, depending on your baby's developmental stage, a swaddle or sleep sack. Your baby's age, development, room conditions and bedtime routine will help determine what you need. Always follow current safe-sleep guidance and the instructions provided with each product.

What is the difference between a sleep sack and a swaddle?

A swaddle wraps around a young baby's body and typically keeps the arms contained, while a sleep sack is a wearable sleep layer generally designed to leave the arms free. Stop swaddling when your baby shows signs of trying to roll, and follow current safe-sleep guidance and the product's instructions.

How do I choose the right baby sleep sack?

Choose a baby sleep sack by checking your baby's measurements against the product's size chart, then consider the TOG rating and room conditions. It should fit according to the manufacturer's guidance, particularly around the neck and arm openings. Check the individual product instructions before choosing a size or TOG.

What should a baby wear under a sleep sack?

What your baby wears under a sleep sack depends on room temperature, the product's TOG rating and manufacturer guidance. Warmer and cooler conditions may require different sleepwear layers, so follow the recommendations provided for your specific sleep sack rather than using the same combination year-round.

What materials are best for baby sleepwear?

There is no single material that is best for every baby or season. Consider softness, fabric weight, breathability, construction, care requirements and the conditions in which the sleepwear will be worn. Loulou Lollipop uses materials including TENCEL™ Lyocell and muslin across selected sleep products.

How do I choose the right size baby sleepwear?

Check your baby's current measurements against the size chart for the specific sleepwear product rather than choosing only by age. For sleep sacks, pay particular attention to the fit around the neck and arm openings and follow the individual product's sizing instructions.

What is TOG and why does it matter for baby sleep sacks?

TOG (Thermal Overall Grade) indicates the level of thermal insulation provided by a sleep sack. A lower TOG generally provides less insulation, while a higher TOG provides more. Consider the TOG rating together with room temperature, clothing layers and the manufacturer's guidance when choosing an appropriate option.
