I want to purchase a sleeping aid for my five month old son, but can't decide which one. Should I go with the comfy lift bed, RESQ wedge, or the Tucker wedge. I have recreated my own version of the comfy lift bed with a propped up crib mattress and rolled up towels and blankets. The first night my son slept 7 straight hours, but the next night it was back to waking every four to eat (3 weeks ago). I'm a new member so I can't access the "Yay or Nay" thread. I would appreciate any feedback.
