How do I choose the right product for my child?
Finding the perfect product for your child is a simple 4 step process: 1. To select the right sleep garment for your child, identify their developmental stage first. Is your baby still in the newborn swaddling stage? Select one of our Swaddle Up™ products. Has your child shown signs of trying to roll over, then choose one of our Transition Bags/Suits. If your child is already mobile and on the move then our Sleep Bags and Sleep Suits are right for you. 2. Once you’ve determined the right developmental stage, you need to determine the room temperature of the room your child sleeps in. Based on that temperature you can choose the right TOG and fabric grade. 3. Select from a number of fabrics, prints, colours. 4. Choose your child’s size.
What should my baby wear underneath based on the TOG and room temperature?
Layer based on room temperature: in warm rooms (24°C+), a short-sleeve vest under a 0.2 TOG is sufficient. In cooler rooms (18–21°C), add a long-sleeve bodysuit under a 1.0 or 2.5 TOG. Always check your baby's chest or back (not hands or feet) to gauge warmth. If it feels clammy or hot, remove a layer.
Which TOG should I choose for my baby, and what room temperatures suit it?
As a general rule, go lighter in summer and heavier in winter: 0.2 TOG for hot nights, 1.0 TOG for mild autumn and spring weather, and 2.5–3.5 TOG for cold winter nights. Every home is different, so use our TOG guide to find the exact rating for your baby's room temperature. If you're between TOGs, adjust with a layer underneath rather than sizing up.
When should I choose a the 3-stage sleep system?
The Love to Dream™ 3-stage sleep system takes your baby from birth to 4 years with products designed for each sleep phase: Stage 1 (Swaddle Up™, 0–3 months), Stage 2 (Transition Bags/Suits, 3–12 months), and Stage 3 (Sleep Bags/Suits, 6 months–4 years). Choose your stage based on your baby's age and whether they're showing signs of rolling. Safety drives the transition, not a fixed date.
When should I choose a Stage 1?
Stage 1 is designed for newborns aged 0–3 months who benefit from secure swaddling to calm the startle reflex. The Swaddle Up™ lets babies sleep in a natural Arms Up™ position, with hands near their face for self-soothing and no loose blankets in the cot. If your baby is under 3 months and not yet rolling, Stage 1 is the right place to start.
When should I choose a Stage 2?
Stage 2 is for babies aged 3–6 months who are beginning to roll and need their arms free. The Swaddle Up™ Transition Bag has zip-off wings so you can gradually free one arm, then both, making the move away from swaddling gradual and less disruptive to sleep. Start transitioning as soon as your baby shows the first signs of rolling, regardless of age.

The Love To Dream™ 3-Stage Sleep System is designed to support your baby’s sleep from newborn to toddler. The Swaddle Up™ (Stage 1 - from day one) offers a snug fit, allowing newborns to sleep with their hands up, promoting self-soothing and reducing the startle reflex. The Transition Bag or Transition Suit (Stage 2 - 3-6 months) helps babies gradually move to arms-free sleep with zip-off wings, ideal for rolling babies. Sleep Bags and Sleep Suits (Stage 3 - 6+ months) provide a safe, cozy, and wearable blanket option for older babies and toddlers, supporting independent sleep with freedom to move.
Choosing the right Love To Dream™ garment for your baby is easy and ensures comfort, safety, and a good night’s sleep. First, identify your baby’s developmental stage Stage 1 for swaddling newborns, Stage 2 for transitioning to arms-free sleep, and Stage 3 for independent sleepers. Next, consider the room temperature to select the appropriate TOG rating for warmth. Then, choose the fabric — we offer options like soft cotton and breathable viscose from bamboo. Pick your favorite print and color from our selection. Finally, choose the right size: use your baby’s weight for Stage 1 and 2, and height for Stage 3.
