The number of baby sleep sacks a baby needs can vary, but generally, 2 to 4 sleep sacks are ideal. This ensures you always have a clean one while others are in the wash. Hushabye sleep sacks are designed for easy care and long-lasting comfort, offering the perfect balance of warmth and breathability. Having a couple of extras also helps accommodate for different temperatures—one for warmer nights and another for cooler evenings. Rotate them regularly to keep your baby cozy and safe while minimizing laundry hassle.
