Children who grow up using kindersack baby sleeping sacks get used to them! Even when they move to a twin or larger bed they still want the security of their kindersack. AND, most importantly, they'll stay warm all night! Traditional blankets and comforters can easily be kicked off and children will cry at 2am if they get cold! Using the kindersacks even in larger beds is such a great idea to help babies sleep through the night!
