I plan on getting a My Brest Friend Twins Plus Deluxe Nursing Pillow but was curious about the Boppy Pillow or Boppy Newborn Lounger to just place the babies on to hang out/tummy time. Has anyone used either the Boppy or Newborn Lounger just for that reason alone? Is it worth it to get it or should I just put them on an activity mat or blanket?
