Ensure your kids will be warm
If the power goes out and you don't have any heat, it may start to get chilly in your kids room at night. A few things that you can do are have a sleepover so the whole family is in one room, use a pack-n-play if you don't bedshare and your little one is in a crib or make a floor bed for everyone. Ensure you're always following safe sleep guidelines.
Most importantly, ensure you're dressing your kiddos for a cooler sleep.
If your child is less than 1 year old, add an extra layer (ie. a onesie underneath their footed jammies) and/or putting them in a warmer sleep sack (with a higher TOG).
If your child is over 12 months, you can add layers and a warmer sleep sack as well as adding an extra blanket for them to snuggle with.
