How do I keep my baby warm without blankets in the crib?

Safety experts advise against using loose blankets in the crib due to suffocation risks. Instead, opt for a wearable sleep sack, which keeps the baby warm and snug without the risk of the fabric covering their face. In warmer climates, a simple full-covered nightsuit is often sufficient, as babies can overheat easily; check their temperature by feeling the back of their neck.
