Frequently Asked Questions
Are wearable blankets safe for toddlers moving out of the crib?
Yes — wearable blankets designed to replace loose bedding are safe when they fit properly and are used according to the manufacturer’s sizing guidance. They help reduce the risk associated with loose blankets while providing consistent warmth. Always follow safe-sleep recommendations and ensure the neck and arm openings fit snugly without being restrictive.
How do I pick the right size to avoid frequent upsizing?
Measure your child’s height and weight and check the brand’s size chart. Pick the size that matches current measurements rather than guessing growth. Choose cut and sack-rooming — 'hip-healthy' or roomy designs give stretch for comfort but still require upsizing if your child grows quickly.
How warm are TOG 0.5 sleep sacks and do I need extra layers?
TOG 0.5 indicates a lightweight, breathable option best for warm rooms or summer. In cooler bedrooms, add a layer of warm pajamas under the sleep sack or choose a higher-TOG product if your child tends to get cold overnight. Avoid bulky layers that prevent safe fit around the neck and arms.
