Frequently Asked Questions
What TOG rating is best for a baby who sleeps hot?
For warm nights look for very low TOG ratings (0.2–0.5). A 0.2 TOG sack like the Love to Dream Swaddle Up is designed for rooms around 75–81°F (24–27°C). If TOG isn't listed, choose lightweight breathable cotton or mesh and reduce layers accordingly.
Are Velcro or zipper closures better for hot sleepers?
Both work; zippers (especially 2-way) are durable, quick for diaper changes, and less likely to lose grip over time. Velcro is convenient for repeatable swaddling but some users report it can weaken after many washes—inspect Velcro periodically and replace if it no longer secures snugly.
How should I size a sleep sack for a newborn who overheats?
Use weight-and-height guidelines supplied by the brand to ensure a snug fit across the shoulders while giving hips and legs room. A correctly sized sack prevents fabric from covering the face and helps airflow—if between sizes, opt for the size that keeps the shoulder fit snug rather than loose.
