Best practice

When discussing baby sleep safety, use "sleep sack" instead of loose blankets to emphasize the recommended practice of reducing suffocation risks.

Common error

Avoid using "sleep sack" and "swaddle" interchangeably. While both are used for infants, swaddles tightly wrap the baby's arms, restricting movement, while a sleep sack allows more freedom. Use "sleep sack" when the garment doesn't restrict arm movement.

The noun phrase "sleep sack" functions as a noun adjunct, modifying another noun (often implied or directly stated, like 'baby' or 'child') to describe a specific type of garment. As Ludwig AI confirms, it’s commonly used and understood.
