Winter Sleep Guide: How To Choose The Right TOG For Your Baby

This winter, we’re teaming up with Love to Dream to help you pick the right layers, TOGs and sizes for calmer bedtimes, from those first swaddled weeks to toddlers who prefer to starfish. Their 3-stage sleep system makes it simple, and their Organic Cotton & Merino Wool range adds breathable warmth when temperatures drop. (Stage 3 products are supported by The Lullaby Trust.)

TOG guide (winter at a glance)

When it comes to dressing your baby for bed, think about the room they’re in, and the temperature first. Then, pick your TOG and add a light, fitted layer underneath.

• 1.0 TOG: 20–23°C (mild rooms)

• 2.5 TOG: 16–20°C (most UK winter bedrooms)

• 3.5 TOG: 14–16°C (properly chilly / older houses)

Quick check: feel baby’s chest or back. Warm = just right, sweaty = too hot. Every baby and home is different, so remember to check and tweak as needed.

How to layer underneath

In winter, a thin cotton or merino base (vest or long sleeve + leggings/pyjamas) under their sleeping bag is usually spot on. Hands and feet can run cool, so always go by the chest/back for comfort. Love To Dream’s new DreamStretch™ Bamboo layers are perfect here. They’re super soft, stretchy and breathable, designed to sit comfortably under their sleepwear without bulk. The viscose-from-bamboo fabric is naturally moisture-wicking and gentle on sensitive or eczema-prone skin, helping keep little bodies warm, dry and comfy overnight, even in colder weather.

The Love to Dream 3-Stage Sleep System

Stage 1: Swaddle Up™ (newborn to around 3–6 months)

Those little Arms Up wings are the magic. Babies can touch their cheeks or suck their hands to self-soothe, while the snug chest fit helps calm the startle reflex. Parents rave about longer, more settled stretches of sleep, and the twin zip means no 3 a.m. wrestling at nappy time. Hip-healthy shape = wriggle room where it counts.

Stage 2: Swaddle Up™ Transition

Spotting first rolls (or the warm-ups)? It’s time to transition. Start with one arm out, then both. Thanks to zip-off wings/poppers, it’s a gentle, low-stress shift that keeps the comfort they already love.

Stage 3: Sleep Suit™ / Sleep Bag™ (supported by The Lullaby Trust)

Bigger babes and toddlers can rock their favourites: the Sleep Suit (separate legs for walkers and pram straps) or the Sleep Bag (all-round snug). Both come in winter-ready TOGs, with soft, breathable fabrics, two-way zips for quick changes, and roomy, hip-friendly fits for comfy zzz’s.

Why choose Organic Cotton + Merino Wool?

Because winter bedrooms have moods, and this blend does the clever stuff so you don’t have to. Merino keeps little bodies cosy, not clammy: it warms when it’s chilly and lets heat out when they get toasty. The fabrics breathe and wick, so you’re far less likely to find sweaty necks or damp PJs at 3 a.m.

It’s kind on delicate or eczema-prone skin, naturally soft with no scratchy fibres. And it’s made for real life, too: wash after wash, it holds its shape and that snuggly feel, without piling on bulky layers.

Safe-sleep quick checks

• Place baby on their back for every sleep.
• Keep the cot clear (no loose blankets, pillows or toys).
• Choose the right TOG for the room; don’t over-layer.
• Ensure a snug neckline/armholes so the bag can’t ride up.
