When can I begin using your Basic or Ultimate Baby Sleep Bags?

The minimum weight for the 2 month - 2 year Ultimate sleep bag is 10 pounds. The sleep bag should fit snugly across the body to prevent the sleep bag from moving throughout the night. If your child's head can pass through the neck hole when the sleep bag is fastened, or if your child is under 10 pounds, the sleep bag should not be used. Your child will need additional time to grow into the sleep bag. As always, we recommend selecting the sleep bag that best matches your child's height and weight.
