The Baby Sling Support Pillow, made from amazingly soft organic cotton jersey, is a great accessory for the baby slings offered at ModMomMaternity.com! It is a specially designed pillow, made to slip into your baby sling under your infant's back and neck, keeping your newborn in the perfect position for the first few months until greater neck strength develops. It is designed to provide extra support for the neck and spine of infants under 9 pounds. Later, it can be used as their first pillow when they sleep in a toddler bed!
