Sleep sacks

Q: What does TOG mean?

TOG is a fabric warmth rating. Each maker publishes its own room-temperature chart; use the chart for the product you have. Safe sleep: see the AAP's guide to safe sleep and NICHD Safe to Sleep. Check the label and the maker's instructions, and ask your pediatrician about your child.

Wearable blankets with arms free. Pick the TOG by room temperature.
