A sleeping bag prevents your toddler from kicking off the covers during the night, pulling the covers over their head, or sliding down under the blankets. You can cuddle your toddler to sleep in their bag & then lay them down in their own cot without disturbing them. Wherever your toddler sleeps, they will feel safe & secure in the familiar comfort of their bag. Please check that your toddler's head cannot easily pass through the neck hole when the poppers are fastened.
