What Should My Baby Wear to Sleep at 22°C? (UK Guide)

When the room is 22°C, it’s usually warm enough that lighter layers work best. The goal is simple: keep your baby comfortable without overheating. Below are easy outfit ideas, plus a quick checklist to help you decide what’s right for your baby.

Quick note: Every baby is different. Use this guide as a starting point and check your baby’s chest or the back of their neck (not hands and feet) to judge comfort.

How to choose the best option (simple checklist)

·      Does your room stay around 22°C all night? Start with 1.0 TOG + a vest.

·      Does your baby often feel warm or wake sweaty? Use a lighter base layer.

·      Does your home cool down later in the night? Keep 1.0 TOG but choose a slightly warmer base layer (like a baby grow).

Comfort check (the easiest way to avoid overheating)

Hands and feet can feel cool even when your baby is comfortable. Instead, check your baby’s: - Chest/tummy, or - Back of neck

If they feel hot, sweaty, or clammy, remove a layer.

Common mistakes at 22°C

·      Over-layering “just in case”

·      Using a thick baby grow under a warm TOG

·      Forgetting that room temperature can rise in the evening (heating, hot water bottles, tumble dryer heat, etc.)

Product pairing suggestions

·      For babies: 1.0 TOG + a soft vest is a simple go-to.

·      For toddlers who move a lot or stand up in bed: a 1.0 TOG sleeping suit can be a practical choice.
