Query: Twins can't sleep without their "B"

These were given to us as a gift, but we truly could not live without them. Starting at 4 months, our boys were able to find their pacifiers in their cribs when they woke at night WITHOUT MY HELP. Our physical therapist was amazed at the dexterity it taught them at such a young age, too. They would feel down each appendage until they found their pacifier and then plop it in their mouth. I now give these as a gift to all of my expecting friends and family members.
